feat(settings): player bar layout — per-control visibility toggles (#627) (#721)

Adds a new sub-section under Settings → Personalisation (Advanced) that
hides individual controls in the player bar: Star rating, Favorite
(heart), Last.fm love, Equalizer, Mini player. Last.fm love still only
renders when a Last.fm session exists; the overflow row in the player
collapses when both Equalizer and Mini player are hidden.

- New `playerBarLayoutStore` (Zustand + persist, items[{id, visible}] +
  rehydrate sanitize) following the queueToolbar / playlistLayout
  pattern; defaults to all visible.
- New `PlayerBarLayoutCustomizer` reuses the same row + toggle pattern
  as the other personalisation customisers.
- Gates threaded through `PlayerTrackInfo` (3 controls), `PlayerBar`
  (EQ + Mini buttons), and `PlayerOverflowMenu` (EQ + Mini in the
  overflow row, with row-level conditional).
- `PersonalisationTab`: added as the last advanced sub-section so it
  only appears when the global Advanced Mode toggle is on.
- Settings search index gets entries for both Playlist page layout and
  Player bar (playlist row was missing).
- New i18n keys `settings.playerBar*` in all 9 locales.

Reuses kveld9's design from PR #627; not merged because the locale
split and the Advanced Mode refactor landed afterwards. Credited via
Co-Authored-By trailer + a new line in settingsCredits.ts under the
existing kveld9 entry.
