fix(album): hide Artist Bio button on Various-Artists compilations (#733)

* fix(album): hide Artist Bio button on Various-Artists compilations

The Album header showed an Artist Bio button on every album, but
when the album artist label is "Various Artists" / "Various" / "VA"
or a language equivalent there is no single artist to fetch a bio
for — the button opened an empty modal. Hide both the mobile icon
and the desktop button when the label matches that heuristic.

 * The Info tab rendered one frame on each track switch with the previous track's artist image URL paired with the new track's cache key — **`CachedImage`**'s IndexedDB then persisted that mismatched blob, so every subsequent track stayed stuck on the previous artist's image. Artist info and song detail are now held as **`{ id, info }`** tuples and the image render is gated on id-match, so source and cache key always come from the same track.
