fix(aiui): play the node's own files before reaching for the network

usePlayer.play() never looked at song.sources[] — a real library track went
straight to (CSP-blocked) Wavlake and reported 'Not found on Wavlake' while
its bytes sat on the operator's disk. Node sources (same-origin /content/<id>,
Range-streamed) now play first; Wavlake is the metadata-only fallback.

FilmDetail likewise only played YouTube sources; own/peer/IndeeHub sources
(same-origin, media-src 'self') now win, YouTube stays the free-films
fallback.
