Subject: [PATCH] feat(android): surface queue source on PlayerUiState

Reads MINSTREL_SOURCE_KEY from the current MediaItem's extras and
projects it as PlayerUiState.currentSource. PlayEventsReporter
needs this to tag plays with their originating system playlist
('for_you'/'discover'/'radio:<id>') so the server advances the
right rotation.
