Scan queue handler now returns a QueueLibraryScanResult enum (Queued|NotFound|SyncDisabled|AlreadyScanning) instead of a lying bool; LibrariesController.ScanLibrary maps them to 202/404/422/409 with ProblemDetails. Guard the lock->enqueue with the EnqueueWithTraktLock compensating-unlock pattern. ScannerService now releases every library/collection lock in a finally so a handler exception can't leak the lock. Plex "Shows" scheduler batch (one lock, two messages) now has only the trailing SynchronizePlexNetworks carry the single release (Unlock flag), mirroring the scheduler Trakt tail-token precedent. Guard the other lock->enqueue producers (Create/UpdateLocalLibrary, UpdateTraktList) with compensating unlock. SPA drops the PENDING_GRACE_TICKS heuristic now that the POST reports 202/409/404/422 directly: 202 -> pending+poll, 409 -> reconcile (no error toast), 404/422 -> surface error.
