posponerAlarma() and posponerProximaDesdePreaviso() called the native scheduler with no error handling, unlike guardarAlarma(). When the native call failed (e.g. revoked exact-alarm permission), the exception escaped before notifyListeners() ran, leaving the alarm list stuck on stale data with no real alarm scheduled and no snooze countdown notification. Both methods now mirror guardarAlarma()'s pattern: permission pre-check, try/catch into _error, and an unconditional notifyListeners() so the UI always reflects the outcome. Failures surface via SnackBar in the ringing screen and in app.dart's postpone-next handler.
