- Bump confirm dialog z-index to 200000 (both #confirm-modal-overlay and
.confirmation-modal-overlay) so they always appear above all other modals
- Normalize track data in _run_sync_task before storing in original_tracks_map:
album as dict {'name': ...} and artists as [{'name': ...}] — fixes all
source converters (Deezer, YouTube, Tidal, Spotify Public, ListenBrainz,
Beatport) whose fallback paths stored plain strings, causing the wishlist
UI to show "Unknown Album" for every synced track
