fix: use r.album.sortName for album name — Navidrome only exposes sortName on album objects

Song objects carry sortName for title only, no album/artist sort fields.
Album sort is only available on the album object itself (r.album.sortName).
Updated loadAlbumDetail to use the fresh API response album, not the nav album.
Simplified dispAlbum to not check non-existent song sort fields.
