feat(eq): add per-device equalizer with 4-level preset resolution

Introduce multi-device EQ support allowing each audio output device (built-in speaker, wired, USB, individual Bluetooth by MAC) to have its own equalizer preset, combined with existing per-station presets for a full station×device matrix. - Add DispositivoAudio model and ServicioDispositivoAudio interface - Add Android platform channel (AudioDeviceCallback) for device detection - Add iOS AudioDevicesPlugin (AVAudioSession route tracking) - Extend ServicioEcualizador with device and matrix persistence keys - Implement 4-level resolution: matrix > station > device > global - Add advanced EQ settings section with feature toggle (off by default) - Extend export/import to v3 with backward compatibility - 184 tests passing, zero analyzer issues
