feat(display): Sprint 7 — USB serial link to AR-Concentrador via NMEA $PARP

Browse Source 
- Add flutter_libserialport dependency (pubspec.yaml)
- New ParpCodec: XOR-checksum NMEA parser + command builders for all PARP sentences
- New ConcentradorService: manages two independent COM ports (RX-OUT broadcast,
  TX-IN commands) at 115200/8N1; auto-fires onConnectionChanged on link drop
- AutopilotState: dual-mode operation (demo timer OR live serial); connectToSerial /
  disconnectSerial; command methods (engage/disengage/adjustSetpoint) forward to
  ConcentradorService when connected; falls back to demo on disconnect
- New PortSettingsScreen (/settings/ports): RX+TX dropdowns populated from
  SerialPort.availablePorts, persisted in SharedPreferences; Connect/Disconnect
  buttons with error display and snackbar feedback
- main.dart: auto-connect to saved ports on startup (silent fail → demo mode);
  registers /settings/ports route
- CockpitScreen: gear icon replaced with PopupMenuButton (Puertos COM / Apariencia)
