Mirrors the play overlay on ArtistCard from /library/artists: fetches
every track for the artist (server already filters per-user
lidarr_quarantine), shuffles client-side, kicks off playback. Adds a
LikeButton next to it with entityType="artist" so the operator can
favourite an artist from this surface without bouncing back to the
library grid.
Play button is disabled when album_count === 0 or while the fetch is
in flight, so a double-tap can't start two queues.
