feat(audio): looping per-season background music system

MusicService (looping audioplayers player, independent of SFX) driven by the active season theme's new 'bgm' key; switches track on season change, pauses on app background, all failures swallowed. Separate Music on/off toggle in Settings (persisted, independent of SFX). Season packs carry bgm keys (menu/season_001/ season_002), manifest regenerated. Assets slot assets/audio/bgm/ ready — drop in menu.mp3/season_001.mp3/season_002.mp3 (CC0) and it plays; silent until then. 180 tests green, analyze clean.
