fix(repair): close active backend before rollback restore

Browse Source 
Rollback cleanup was instantiating a fresh ChromaBackend, so the live backend that had opened the PersistentClient could keep file handles alive during restore. Close the active backend instance instead so rollback and CLI recovery can release Windows-safe locks before copying the backup back into place.
