Replace Spotify show embed on /episodes with custom player; v1.1.6

LatestEpisodePlayer fetches the most recent episode from /api/episodes
(Anchor RSS) and renders it with the centered cinematic layout. The
Spotify show iframe is removed; platform buttons and HeadlinerWidget
remain below as before.
