test(deferred): coverage for the bulk deferred-items cleanup

Ten tests spanning the eight commits in this branch:
- Player end-screen markup present (overlay + ring + cancel hooks).
- C hotkey binds to #ytpLyricsBtn in the player keydown handler.
- Guest Subscribe button carries ?intended= and encodeURIComponent.
- /@handle/videos 302s to the hash URL; nonsense tabs 404.
- /channel/{username}/videos/more returns a cursor-paginated JSON
  payload with items + next_cursor + has_more.
- /studio redirects anonymous visitors to login.
- /studio renders only the signed-in user's videos.
- Studio bulk visibility + bulk delete scope updates to Auth::id().
