feat(web): Most Played horizontal compact tiles + revert Rediscover

Operator clarification: the 'compact like the app' request was for
Most Played, not Rediscover.

- CompactTrackCard rewritten as a horizontal Row: cover thumbnail
  left, title + artist column right. w-72 (~288 px) matches the
  Android CompactTrackTile's 176 dp visual weight. Most Played's
  existing chunked-rows-in-shared-scroller layout now reads like
  the Android multi-row LazyHorizontalGrid.
- Rediscover steps back from the compact w-32/w-28 widths to w-40/
  w-36 (the pre-PR-#66 sizes) — the size hierarchy still works
  with the regular AlbumCard treatment.
