add session-gated /sync endpoint and prune stale vectors after reindex

SyncController/SyncService/SyncProvider mirror the existing search dispatch pattern: a session-gated controller routes a SyncRequest to the provider registered for its ServiceType. HomeboxSyncProvider pages through the full Homebox catalog, embedding each page via EmbeddingService, and now collects every item ID it sees across all pages before pruning anything no longer present upstream in one deleteStaleVectorEntries call at the end - deleting per page would treat items on other pages as stale and wipe them out.
