console: bump vite-plugin-svgr to 5 and jsdom to 30 - #39683

### Motivation

`yarn gen:types` fails with `function "pg_get_serial_sequence" does not
exist`. kysely-codegen runs kysely's Postgres introspector for its table
query. Since the bump to kysely 0.28 (#35669), that query calls
`pg_get_serial_sequence`, which Materialize lacks. kysely 0.29 still
does. The query also lists only relkinds `r`, `v` and `p`, so the
catalog's builtin materialized views (`m`) never reached the types under
kysely-codegen 0.17. #40044's types were generated with both patched by
hand in `node_modules`.

This also bumps kysely to 0.29 and kysely-codegen to 0.20, superseding
#39686.

### Description

- `bin/kysely-codegen.ts` runs kysely-codegen programmatically with an
introspector that overrides only the table query. kysely-codegen's
materialized view query, enum handling and serializer still apply.
- The script writes the copyright header to `types/materialize.d.ts`.
The codegen output lacks it, and the copyright lint fails without it.
- `bin/generate-types` exits on errors, pulls the requested image (a
cached `latest` went stale), and stops the container on exit. Before,
each run left a container bound to port 6875, and the next run generated
types from that old container.
- kysely 0.28.17 → 0.29.8 and kysely-codegen 0.17 → 0.20.0:
- 0.29 rejects `limit(sql.raw(...))`. `rawLimit` and the lag history
limit now call `query.limit(sql.lit(n))`, which still inlines the limit
as a literal, as Materialize requires.
- `rawLimit` used to append its limit with `modifyEnd`. In 0.29,
compiling end modifiers calls `Array.prototype.toSorted`, which Chrome
109 lacks. No console query uses end modifiers now. Neither `rawLimit`
caller has an OFFSET or another end modifier, so the compiled SQL is
unchanged.
- kysely 0.29 is ESM-only and kysely-codegen 0.20 `require`s it, so
`yarn gen:types` needs Node 22.12 or later. CI and the Volta pin run
Node 26, and #39683 updates `engines.node`.
- `types/materialize.d.ts` is regenerated against v26.49.1.
kysely-codegen 0.17 and 0.20 produce identical output.
  - Adds `mz_builtin_columns` and `mz_builtin_index_columns`.
- Builtin columns lose their `Generated<>` wrappers, because #40316
changed `pg_attribute.atthasdef` to report no default for them. The
console only selects from these relations, where `Generated<T>` and `T`
read the same.
- Drops the two hand-added `TODO` markers from #39992. The generator now
emits `mz_cluster_auto_scaling_strategies` and
`mz_cluster_reconfigurations`, and `AUTO_SCALING_MIN_VERSION` still
gates them at runtime. The file is now exactly the generator output.

Worth checking on the preview, since these run the changed limits:
- the Query History list;
- a sink's Errors tab;
- the freshness lag charts on the environment overview and the cluster
pages.

### Motivation

Supersedes #39655. Dependabot's version of this bump fails typecheck and
several unit tests.

### Description

msw is only used by tests.

- `request.clone()` now keeps the declared body type, where msw 2
returned a plain `Request` whose `json()` was `any`. The three SQL
handlers that destructure the body now declare it with `http.post<never,
ExtendedRequest>`.
- `HttpResponse` is now generic, so two pending handlers resolve a plain
`Response`.
- `onUnhandledRequest` is renamed to `onUnhandledFrame`. msw 3 ignores
the old name at runtime, so keeping it would let unhandled requests
reach the real network instead of erroring. `vitest.setup.ts` uses the
new name.
- msw 3 answers a few ticks later, so `AlterClusterModal`'s "closes the
modal on success" test now waits for `onClose` instead of checking right
after the click.

- **Test server:** msw 3 mocks Node's `fetch` at the socket level
(undici). When a test aborts an in-flight request, undici opens a
replacement socket it never writes to. msw passes that idle socket
through to the real network, and the next fetch can reuse it and fail
with `fetch failed`. That made a few tests flaky under CI load.
- `src/api/mocks/server.ts` now builds the server with msw's
`defineNetwork` and the interceptor that patches `fetch` directly, so
mocked requests never touch undici.
- This uses msw's experimental API, with a TODO to return to
`setupServer` once mswjs/interceptors#863 (the upstream fix, still a
draft) ships.
- With faster responses, one Object Explorer spinner test now holds its
request open, as its sibling tests already do.

msw 3 requires Node 22.12 or later. CI and the Volta pin run Node 26,
and #39683 updates `engines.node`.

### Verification

Existing tests, plus five consecutive full-suite runs on Node 26 (CI's
Node version) with no failures.

### Motivation

`console/package.json` declares `"node": ">=20.12.2"`, but the installed
dependency tree no longer runs there. Checking every installed package's
`engines.node` against candidate versions:

| Node | Packages whose `engines.node` rejects it |
|---|---|
| 20.12.2 | 60 (jsdom's CSS packages, …) |
| 20.19.0 | 18 (`@mswjs/interceptors` 0.45, `@rolldown/plugin-babel`,
`@testing-library/jest-dom` 7, `eslint-plugin-unicorn` 79, …) |
| 22.12.0 | 25 (`@eslint/*` needs 22.13, …) |
| 22.18.0 | 7 (`node-gyp` 13, `which` 7, `abbrev` 5, `nopt` 10,
`lint-staged` 17, `undici` 8.12, …) |
| 24.11.0 | 5 (`node-gyp` 13 and its helpers) |
| 22.22.2, 24.15.0, 26.0.0 | none |

msw 3 (#39684) and kysely 0.29 (#40550) both deferred this change to
#39683, which is still open.

### Description

`engines.node` becomes `^22.22.2 || ^24.15.0 || >=26.0.0`, the
intersection of every installed package's range. Volta (26.10.0),
`console/Dockerfile` and CI already run Node 26. It is the same range as
#39683, so that PR merges cleanly on this line.
