Persist organize_by_playlist on mirrored playlists and run playlist-folder
downloads from the auto-sync pipeline instead of the global wishlist phase.
Register SoulSync library rows after playlist-folder post-processing, route
failed organize batches to the wishlist correctly, and skip sync-time
unmatched wishlist only when organize download handles retries.
Invalidate stale playlist track caches on refresh (Spotify and Deezer ARL),
re-mirror on refetch, and improve standalone playlist modals (re-analysis,
Open in Mirrored). Add filesystem missing-track detection and tests.
