A toggle from the Android Auto notification or a preset picked from the
car's EQ folder mutated PluriWaveAudioHandler state directly, leaving
EstadoEcualizador (and therefore the phone UI) unaware and never
persisting the change, so it was lost on the next app restart.
Forward the handler's ecualizadorActivo flag through ServicioAudio and,
mirroring EstadoRadio's existing playFromMediaId resync, diff it plus
presetActual against the cached values on every estadoStream tick,
adopting and persisting a divergence via ServicioEcualizador.
