Media player: pause→stop, display fix, remove dead is_paused checks

on_pause converts to immediate media_player.stop (PAUSED holds 8KB
internal RAM + HTTP connection + ring buffer — useless limbo state).
Xiaozhi on_play shows neutral mood image (clears old VA text first).
Remove all media_player.is_paused conditions (state is now transient).
