Add GET /api/media-sources/collections-scan-status (MediaSourcesController →
GetCollectionsScanStatus handler) reporting which media-source families
(plex/jellyfin/emby) currently hold their external-collections scan lock,
reading IEntityLocker.Are{X}CollectionsLocked(). The lock is family-global
(no source id) and boolean (no percent), so the DTO carries just {family} and
returns only active families — the counterpart to GET /api/libraries/scan-status.
SPA: useCollectionsScan now polls this endpoint and reconciles optimistic
pending against the active-family set (seeding on mount so an in-progress scan
disables buttons immediately), using the same grace-tick helper as library
scans (now generic over the pending key type). Drops COLLECTIONS_PENDING_TIMEOUT_MS
— a long deep scan no longer re-enables the button early, and a fast scan no
longer wedges it disabled for the full timeout. A row shows Scanning when its
family is active or it has an in-grace optimistic pending key.
Tests: handler (3), controller route+delegation (2), SPA api fn + hook reconcile
(mount-seed / 202-promote / 409-keeps-disabled / 404-error). OpenAPI + TS types
regenerated. Docs: api-conventions §3b, blazor-route-parity §5, decisions.md.
Unblocks #91b (arc item 4): Libraries.razor's collections-scan affordance now
has full authoritative parity.
