chore: link the FOSSA license scan for CLOMonitor - #4899

## What this PR does

Implements the release-asset part of #4759: a release cut from a tree
that has this change gets an SBOM of its source and one keyless
signature that covers all of its assets.

These are the two CLOMonitor checks still failing for this repository,
`sbom` and `signed_releases`, after #4757 and #4899 brought the project
score to 96.69.

`hack/upload-assets.sh` now collects its asset list into an array and
hands it to the new `hack/sign-release-assets.sh` before the first
upload. The script writes three files into `_out/assets`, and they are
uploaded with the rest:

| File | What it is |
|---|---|
| `cozystack-source-sbom.spdx.json` | SPDX 2.3 SBOM made with syft, over
`git archive HEAD` (the committed release tree, without `_out/`,
`.release-tooling` or runner leftovers) and the unpacked
`cozypkg-*.tar.gz` binaries. It does **not** describe the container
images that `packages/` pins by digest (their SBOMs are #2937, A2 in
#3278) or the Talos ISO, disk, kernel and initramfs images. It is named
by what it covers, so `cozystack-sbom` stays free for an SBOM of the
release as a whole. CLOMonitor's `sbom` check matches `sbom` in an asset
name. |
| `cozystack-checksums.txt` | SHA-256 of every uploaded asset and of the
SBOM. |
| `cozystack-checksums.txt.sigstore.json` | Sigstore bundle of `cosign
sign-blob` over the checksums, keyless, signed with the job's GitHub
OIDC identity. |

Before it returns, the script runs the same `cosign verify-blob` that
`docs/release.md` gives users, with `--certificate-identity-regexp
'^https://github\.com/cozystack/cozystack/\.github/workflows/(tags\.yaml@refs/tags/v|promote-rc\.yaml@refs/heads/main$)'`:
`tags.yaml` on a `v*` tag push, `promote-rc.yaml` dispatched from
`main`. A signature that check would reject therefore fails the job
before anything is uploaded. It also refuses its own three outputs as
inputs: `promote-rc.yaml` downloads every rc asset, and a stable release
has to get freshly computed checksums and a fresh signature, since
promotion restamps several assets.

Workflows: `tags.yaml::prepare-release` and `promote-rc.yaml::promote`,
the two jobs that call `make upload_assets`, get `id-token: write` and
two setup steps:
- syft v1.54.1 from its release tarball, checked against a committed
SHA-256 (`c069905b…`, the release's checksums entry; the checksums file
verifies against anchore/syft's keyless release signature). Not
`anchore/sbom-action/download-syft`: pinned by commit, it still runs
syft's `install.sh` fetched from a tag at run time, in a job that holds
the app token, the GHCR login and `id-token: write`. v1.54.1 is past
GHSA-mw2c-m758-9v5q (fixed in v1.52.0).
`hack/ci-tool-installs-contract.bats` now fails on
`anchore/sbom-action`, on a syft install script, on a syft download
without `sha256sum -c` and on version or checksum drift between the two
workflows.
- `sigstore/cosign-installer` v4.1.2, pinned by SHA, with
`cosign-release: v3.1.3`: the version `docs/release.md` asks users for,
so the job checks its own signature the way they will. The action
verifies that binary against cosign's keyless and KMS bundles with its
digest-pinned bootstrap cosign. `hack/ci-tool-installs-contract.bats`
holds the action commit and the release equal in both workflows and
fails on a step without `cosign-release`.

`docs/release.md` gets a "Release signatures and SBOM" section with the
user-side verification: cosign v3.1.3 or later (v2.6.5 on the v2 line),
the two commands joined with `&&`, what the SBOM covers and what the
certificate identity proves. It now also says, at each place
`promote-rc.yaml` is run, that it is dispatched from `main` only.

### Decisions for the release owners

- **Fail closed.** If Fulcio or Rekor is down, the release job fails and
nothing is uploaded. I chose that so that no release goes out unsigned.
If you would rather publish unsigned than block, the change is a `||
echo ::warning::` around the call in `upload-assets.sh`.
- **Promotion runs the rc tree's script.** `promote-rc.yaml` calls `make
upload_assets` from the rc checkout, not from `.release-tooling`. The
first signed stable release is therefore the promotion of the first rc
tagged after this merges. `release-1.6` gets signatures only if this is
backported. CLOMonitor reads the latest release, so the score moves only
when that release carries the files.
- **Certificate identity pins the refs** (decided in review):
`tags.yaml@refs/tags/v…` and `promote-rc.yaml@refs/heads/main`. A
`promote-rc.yaml` dispatched from another branch fails the job's own
check at the upload step, after the staging branch, the `promotion-*`
candidate and the empty draft release exist; nothing in `parse` refuses
a non-`main` dispatch up front. Until the `v*` tag rulesets exist, a
hand-pushed `v*` tag whose tree has an edited `tags.yaml` still signs,
which `docs/release.md` says.
- **Follow-ups after the first signed release** (#4759 stays open for
them):
- `project.documentation.signature-verification` in
`security-insights.yml` (#4757);
- the SBOM row in `docs/security/self-assessment.md`, which says "Not
published at this time"; the image caveat above stays in it.

I left both alone so that they do not describe releases that don't exist
yet.

### How it was checked

- Bats 1.14.0 (the version CI installs), with gh, syft and cosign
stubbed:
- `hack/sign-release-assets.bats`, 8 tests: what the checksums cover;
that syft sees the committed tree and the cozypkg binaries but not
untracked files; that the verify identity accepts `tags.yaml` on a `v*`
tag and `promote-rc.yaml` on `main`, and rejects a fork, another
workflow, `tags.yaml.evil`, `tags.yaml` on a branch, and
`promote-rc.yaml` on `release-1.6`, on `main-evil` and on a tag; that
`docs/release.md` shows the same regexp as the script; that a failed
verification fails the script; that it refuses a missing asset, assets
split over two directories (with a same-named file in both, so the test
fails if the directory check is removed) and its own outputs as input.
- `hack/upload-assets.bats`, 4 tests, new: the exact upload list and
order (the assets, then the SBOM, the checksums and the bundle); that
the checksums name every upload but the last two; zero `gh` calls when
verification fails or an asset is missing. The old `upload-assets.sh`
fails all four, a version that signs after uploading fails the last two.
- `hack/ci-tool-installs-contract.bats`, 8 tests. Putting
`download-syft` back, dropping the `sha256sum -c` line, letting
`SYFT_VERSION` drift between the workflows, dropping `cosign-release`
from one step, letting it drift, unpinning the installer or giving one
step another installer commit each fails it.
- Putting the old any-ref regexp back in the script fails the identity
test and the docs tie; putting it back in the docs alone fails the tie.
- The meta-suites `bats-strict-setup`, `bats-no-negated-assert`,
`bats-no-exit-trap`, `bats-runner-coverage` and `bats-runner-contract`
pass: 90 tests across these eight files.
- The pinned regexp gives the same accept/reject results under `grep -E`
and Go's `regexp` (what cosign uses). cosign-installer's install script
at the pinned commit, run as written with `cosign-release: v3.1.3`,
verifies the binary's keyless and KMS bundles and installs v3.1.3 (its
SHA-256 matches `cosign_checksums.txt`). `--yes`, `--bundle`,
`--certificate-identity-regexp` and `--certificate-oidc-issuer` are
listed, not deprecated, in cosign v3.1.3's help.
- The `Set up syft` step's script, run as written with
`RUNNER_TEMP`/`GITHUB_PATH` set: the checksum passes and `syft version`
reports 1.54.1. A real syft v1.54.1 run through
`hack/sign-release-assets.sh` (cosign stubbed) over this tree and the
v1.6.5 `cozypkg-linux-amd64.tar.gz` took 10 s and wrote an SPDX 2.3
document with 920 packages: 440 golang, 373 npm, 103 github, 4 without a
purl; 60 come from the cozypkg binary.
- cosign behaviour behind the docs, with a key-signed legacy bundle
whose `cert` holds the bare public key, against the documented identity
regexp (tlog ignored, since an attacker can upload their own entry):
v2.6.4 and v3.1.2 print "Verified OK", v2.6.5 and v3.1.3 reject it.
`--new-bundle-format` makes v2.6.4 reject it but not v3.1.2, so the docs
give the minimum version and not the flag. A real keyless protobuf
bundle (syft's) verifies on v2.6.5 and v3.1.3.
- zizmor 1.26.1 `--offline` reports no findings. actionlint 1.7.12 (with
`.github/actionlint.yaml`) reports the same 13 pre-existing info-level
shellcheck notes in `tags.yaml`/`promote-rc.yaml` as before, nothing
new. shellcheck passes on both scripts. `hack/check-commit-trailers.sh`
passes.
- Not checked: a real keyless signature. It needs the OIDC token of a
job in this repository, so the first rc after the merge is the
end-to-end test. Cutting an `-alpha.N` first would exercise it without
touching an rc.

I checked the trigger map file by file. The only entry
`hack/upload-assets.sh` can trigger is renaming a release asset, because
the website install pages hardcode asset names. This PR adds three
assets and renames none of the released ones, `cozypkg-checksums.txt`
included (the SBOM was renamed to `cozystack-source-sbom.spdx.json` in
review, before any release carried it). The workflow and docs changes
match no entry.

### Release note

```release-note
feat(release): releases carry cozystack-source-sbom.spdx.json, an SPDX SBOM of the source tree and the cozypkg binaries (not of the container or Talos images), cozystack-checksums.txt with the SHA-256 of each asset, and cozystack-checksums.txt.sigstore.json, a keyless Sigstore signature over the checksums made by the release workflow; docs/release.md shows how to verify a download with cosign v3.1.3 or later.
```

## What this PR does

Backports to `release-1.7` from `main`, picked by the rules of the
[backport
policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md)
in merge order. A merged pull request comes as its own commits, picked
with `git cherry-pick -x` so each keeps its author, message and
sign-offs, and a merge commit that carries the original's merge message
with a `Backported-from:` trailer naming it; a squash-merged one comes
as one pick. `backport-batch verify` checks that shape. A pick listed as
changed differs from the commit it came from; `git range-diff
<merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A
conflict or a failing check here is a [backport
task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md).

### Release note

```release-note
fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository.

fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout.

fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line

fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member.

fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade.

fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint.

fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...＠sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time.

fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back.

fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking.

fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts.

fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result.

fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand.

fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing.

fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret.

fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain.

fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged.

fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane.

fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged.

fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase.

fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading.

fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix.

fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring.
```

## What this PR does

Backports to `release-1.7` from `main`, picked by the rules of the
[backport
policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md)
in merge order. A merged pull request comes as its own commits, picked
with `git cherry-pick -x` so each keeps its author, message and
sign-offs, and a merge commit that carries the original's merge message
with a `Backported-from:` trailer naming it; a squash-merged one comes
as one pick. `backport-batch verify` checks that shape. A pick listed as
changed differs from the commit it came from; `git range-diff
<merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A
conflict or a failing check here is a [backport
task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md).

### Release note

```release-note
fix(seaweedfs): bucket users granted together could get S3 keys that never work (403 InvalidAccessKeyId). COSI driver is bumped to v0.4.0, which writes each grant to per-identity IAM file.
```
