mckero a654735337 merge: upstream rt-bishop main (18 commits) with conflict resolution

Merges rt-bishop/Look4Sat main (a42a5f1f, 18 commits: AMSAT status page,
customizable data sources, Doppler calculator, radar compass offset, per-sat
offset memory, localized date formats) into the fork's 30-commit audit
baseline.

Conflict resolution policy (user-directed):
- AMSAT feature (AmSatRepository, SatStatusScreen/ViewModel, SatStatus model):
  upstream version, which the user judged better built. MainScreen routes
  Screen.AmSat through SatStatusDestination().
- Localization: our values-zh/values-tr restored (upstream's merge dropped the
  fork-only strings); new upstream strings (sat_group counts, compass offset,
  frequency offset help) added in EN + ZH.
- fork-only features kept (CW decoder, Mutual/Roaming, WaveLog, APRS, Log tab,
  custom TLE/transceiver source switches): ours.
- Both sides' additions merged where independent: radar compass offset fields
  (Settings/SettingsRepo/RadarState), calculatorOffsetKHz action, wider linear
  transponder detection, deduplicateTransponders + its tests, sunrise/sunset
  tests merged with the moon hour-angle test.
- Sources kept as the fork's map structure (DatabaseRepo depends on it);
  satelliteModes list re-added for SelectionRepo. getSatelliteTypesIds /
  setSatelliteTypeIds re-added to ISettingsRepo+SettingsRepo; SharedDialog
  re-added to Components; providePairedBluetoothDevices added to
  IMainContainer/MainContainer.
- Icons renamed upstream (ic_satellites->ic_sputnik, ic_radar->ic_satellite)
  applied to Navigation/MutualScreen.

Build verified: all modules compileReleaseKotlin + unit tests
(core:domain, core:data, feature:map, feature:roaming) green.

Look4Sat: Satellite tracker

Radio satellite tracker and pass predictor for Android, inspired by Gpredict

Track satellite passes with ease!

Thanks to Celestrak and SatNOGS you have access to over 9000 active satellites.
You can search the entire database by NORAD Catalog Number or the satellite's name.

Orbital positions and passes are calculated relative to your location.
To get reliable data make sure to set the station position via the app Settings.

The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.
It is now and always will be completely ad-free and open-source.

Main features:

Predicting satellite positions and passes for up to 10 days
Showing the list of currently active and upcoming satellite passes
Showing the active pass progress, polar trajectory and transceivers info
Showing the satellite positional data, footprint and ground track on the map
Custom TLE satellite data import is available via Three Line Element .txt files
Offline first: calculations are made offline. Weekly TLE data update is recommended.
