F1: ContainerImageStatus now reads the 24h statusCache (keyed by imageID)
before the remote registry digest lookup, so the cache is effective on the
input side for all callers instead of being write-only. This avoids the
rate-limited registry HEAD on repeat loads.
F2: add nodeName to the imageStatus query key so cached results cannot be
reused across nodes.
F3: correct the swagger annotations to reflect that engine-level issues
degrade to a 200 skipped/error status rather than 400/404.
F4: return a generic error message to the client instead of the raw
registry/engine error; the raw error is still logged server-side.

Add native CE detection of "a newer image is available" for running
containers, surfaced as a read-only HTTP endpoint and a containers-list
badge/column. No applying of updates (M3/M4), no auto-heal (M1).
Backend:
- New CE handler GET /docker/{id}/containers/{containerId}/image_status
backed by the existing zlib/CE digest engine
(images.NewClientWithRegistry + ContainerImageStatus). Honors nodeName,
authz, and routes registry calls through the credential store / SSRF
AllowList. Engine failures degrade to a 200 {Status:"error"} so the UI
stays graceful. Response shape: {Status, Message?}.
Frontend (CE-only, no isBE gating; the EE ImageStatus component is left
untouched):
- useContainerImageStatus TanStack Query hook (5min staleTime, no
refetch-on-focus; backend caches 24h) calling the non-proxied endpoint.
- UpdateStatusBadge component (own assets, neutral on skipped/error).
- "Update available" column in the containers datatable; one cached,
non-blocking query per visible row.
Tests: Go response-shape unit test; vitest for the badge (all statuses)
and the hook (url + nodeName query param via msw).
