feat(instruments): add forecast wind, wave, swell and current from Open-Meteo

- Add swell params to MarineApiService request
- Add swell fields to MarineHourly model
- Add MarineConditions snapshot model
- Add WeatherRepository.fetchCurrentConditions() (first forecast hour)
- Add MainViewModel.loadConditions() + marineConditions StateFlow
- Add Forecast section to instrument sheet: Curr / Wave / Swell
- Populate TWS from forecast wind speed on first GPS fix
- Trigger loadConditions() once on first GPS position received
