feat(hub): consolidate loose tracks, "&"/"and" fold, player close/queue

Album-grid readability, part two:

- groupMusicEntries (music-app.js): an album bucket left with exactly
  one track - a real album tag, but only one song from it, not the
  whole release - clutters the grid the same way an untagged loose
  track does. Both kinds now fold into one "<artist> - Various" tile
  per artist, unless there is only one leftover track overall, where
  relabeling buys nothing and the track keeps its own name (or the
  generic placeholder, if it never had one).
- foldKey also normalizes "&" vs "and" ("Artist & The Band" / "Artist
  and The Band" is one act, tagged both ways across different rips of
  the same catalogue) alongside the existing case/whitespace fold.
- music-player.js: a close button pauses and tears the player down;
  an unmount cleanup effect (pause, revoke every cached blob URL)
  fires either way, whether that's the close button or the shell
  tearing the bar down on its own. A "current queue" button opens an
  overlay listing the whole playing queue with the current track
  highlighted, click any to jump to it - works identically regardless
  of how the queue was built (an album, the consolidated misc bucket,
  a single standalone track), since it only ever reads the player's
  own live tracks/order/pos.
- group-page.js: this component is not remounted when switching to a
  *different* group on the same /group/:id route (only the groupId
  prop changes) - so without an explicit reset, music from one group
  would carry into the next one opened. Resets musicQueue to null on
  groupId change; a tab switch inside one group still leaves it alone.
- Scrubbed real artist/band names that had leaked into code comments
  and test fixtures (enrich_audio.py's docstrings, several
  test_enrich_audio.py assertions, a music-app.js comment) - replaced
  with generic placeholders, no behavioural change.
- i18n: music.various, music.player_close, music.player_queue,
  music.queue_title added across all ten locales.

Client-side only except none of this touches the node at all. npm run
sync-ui re-run. Full suite: 1129 passed, no regressions.
