feat: album list, artist list, and artist detail views

- Fav albums: now shows a sortable list (title/artist/year/tracks);
  double-click opens the album
- Fav artists: now shows a sortable list; double-click opens the artist
- Artist detail page: name, biography summary, and their album list
- Rust ArtistDto gains albums field; get_artist fixed to extra=albums only
- Volume popup minimum width set so "100%" label is never clipped
