bsncubed e5c3c0ad8a Player: runtime source override and play-a-URL on /api/player 
The player now owns the effective mode (config or override) and passes it
down: spotify_apply(enable) and hls_set_url(url) instead of both reading
source.mode from the config. /api/player/source forces spotify|hls|off
(config returns to the saved mode), /api/player/url plays an m3u8 now;
neither is saved. GET reports it in `forced`.
