fix(queue): complete album_id and artist_id propagation for track navigation

Ensure album_id and artist_id are passed through all queue track creation paths:
- trackActions.ts build functions (Qobuz, album, playlist, local tracks)
- Session persistence (both frontend and Rust backend)
- buildAlbumQueueTrack wrapper function
- Session restoration
