test(polish): match channel row, nested-reply, cursor paginator, hotkeys

Four tests covering the post-audit polish commits:
- Match watch page renders the shared .channel-row component.
- Reply-to-reply button carries data-parent-id and data-handle so the
  JS can prefill "@author " when the parent reply form opens.
- liked() controller returns a CursorPaginator instance (controller
  introspection — avoids a 400 KB view render per assertion).
- video-player component ships the ">" / "<" playback-rate hotkey.

Also cleans up a stale ->onEachSide()->links() call in user/liked.blade
that would blow up now that the controller returns a CursorPaginator
(which doesn't support onEachSide).
