feat(web): match track kebab to Android + add it to full-screen Now Playing

Bring the web TrackMenu to parity with Android's canonical TrackActionsSheet
so the kebab reads the same on both clients:
- Reorder to Android's groups: queue → like/add-to-playlist/start-radio →
  go-to-album/artist → hide.
- Drop the duplicate "Flag this track…" item — it opened the very same
  FlagPopover as "Hide" (Android folds flag into a single Hide).
- Align icons (ListVideo / ListMusic / ListPlus / Disc3 / User).
- Admin-only "Remove from library" stays as a web superset (Android has no
  surface for it), past its own divider.

Mount the kebab on the full-screen /now-playing route with hideQueueActions,
mirroring Android's NowPlayingScreen — Start radio / Add to playlist / Hide
were previously unreachable there (only like + volume + queue existed).
