Fix playlist controls: add to type-specific views (music, generic, match)

Controls were only added to show.blade.php, but music/generic/match videos
render their own complete layouts with their own sidebars. Added the
pl-controls-bar to all three type views and the global CSS to app.blade.php.

- music: full standalone JS with shuffle/loop/autoplay + _plOnTrackEnd hook
- generic/match: syncs with video-player's existing ytpShuffleRow/ytpAutoplayRow toggles
- audio-player: ended handler now calls window._plOnTrackEnd if defined
- video-player: exposes window._ytpNav.next/prev for sidebar prev/next buttons
