The album header had several dead icon buttons and a non-navigating label
card. Wire them:
- Shuffle -> play_album_shuffled (SystemTime-seeded xorshift Fisher-Yates,
same as the playlist shuffle, no rand dep) + ("album","shuffle") arm.
- Radio -> existing ("album","radio") album-radio path.
- Artist (user icon) -> open the album artist.
- Label sidebar card -> navigate to the label page; added label-id to
AlbumState (populated from album.label.id) and made the card clickable.
Still pending for AlbumView (next batches): multi-select (square-check +
MultiSelectBar), the "more" ellipsis menu, the digital-booklet viewer, and
add-to-mixtape. Awards pages deferred (1:1 Tauri port, separate session).
