feat(audio): audio session integration and runtime robustness

- Integrate audio_session (new servicio_audio_session.dart): incoming calls pause the radio and resume on end, headphone unplug pauses without auto-resume, permanent focus loss never auto-resumes, duck lowers volume - Add play-intent flag to ServicioAudio so interruption handling and future reconnect logic can distinguish user pause from system-driven stops - Eliminate read-modify-write race in ServicioAlarmas with an in-memory cache and single-writer queue across all mutations; recalcularTodas persists only when state actually changed - Convert ServicioAlarmasAndroid static StreamController/handler to injectable instance fields, restoring test isolation - Inject a single cached SharedPreferences from main.dart across services and state (removes 23 inline getInstance() calls) - Move configurarLocalizaciones out of MiniReproductor.build() (was running on every rebuild during playback) - Bound the alarm fire-dedup set (cap 200 entries, 24h pruning) - 12 new tests (89 total green), flutter analyze clean
