fix(qt): kiosk feedback round — chrome, search, album, artists, lyrics

Address the owner's kiosk feedback on top of the release hardening:

- Chrome: the back bar is a drag surface and shrank to 44px with one shared
  button form for Back/Forward/Connect/Cast; Qobuz Connect and Cast are a
  permanent cluster in the bar; the dead Share-logs button left the kiosk
  Settings header.
- Transport bar: the hidden overflow menu is gone; Volume is always visible
  with a vertical sheet, and Desktop mode has its own button.
- Now Playing: one centred transport row (New-bar order); lyrics are centred
  (shared LyricsLinesView gains an opt-in centered, desktop default false).
- Local Library: the media funnel and an Open (ephemeral) entry point reach
  the kiosk; Artists is its own multi-column round-card grid (kiosk-only, the
  desktop LocalArtistsTab is untouched); the Artists drill-down query no
  longer hangs off a stale derived guard.
- Search: the All-tab dashboard shelves render again — they were mounted in a
  Loader Component that read the delegate id under reuse and bound an empty
  model; they are direct children now.
- Album detail: icon actions the height of the quality badge plus play next /
  later / queue, an inline floating quality badge, and zebra rows; both album
  headers show a quality badge.
- Immersive: a quiet auto-hiding kiosk exit moved to the bottom, clear of the
  window controls.
