Parent: #739
Depends on: BOM tooling issue (will link once filed)

Summary

Add a user-facing docs page that publishes the full container image inventory for AICR — explicit pins, implicit chart-default images, and the registries spanned.

Motivation

Customers performing security review or planning private-registry mirrors today have to manually render Helm charts to discover what AICR deploys. A published inventory removes that burden and reduces support load.

Proposed content

Add docs/reference/container-images.md (or similar) covering:

1. Per-component image table — for each of the 23 components: chart host, chart name, pinned version, runtime image registries, link to upstream chart.
2. Explicit vs implicit — explanation of which images are pinned in AICR vs inherited from chart defaults, and the trade-offs (upgrade flow vs reproducibility).
3. Registry list — every public registry AICR can pull from, with rationale for each (NGC, ghcr.io, gcr.io, ECR, quay.io, registry.k8s.io, cr.kgateway.dev, Docker Hub).
4. How to enumerate yourself — pointer to make bom once available.

Success criteria

• Page is auto-generated or kept in sync via the BOM tooling (no manual list to drift).
• Linked from docs/user/component-catalog.md and the security/integrator sections.
• Passes lychee link check.
