fix(gps,data): official-code fixes - real GPS result callback, no fake update success (4.5.2, release pending)

Official code issues found during review (user-reported):
1. GPS "success" was shown instantly even when no fix was obtained:
   - setStationPosition() always returned true (permissions exception
     swallowed, async requestLocationUpdates without waiting)
   - now: suspend + LocationManagerCompat.getCurrentLocation (GPS
     first, network fallback), permission check upfront, 15s timeout,
     success only when onLocationChanged fires; SettingsRepo takes
     Context for the permission check; ViewModel waits for the real
     result and shows "Unable to get location - check permission and
     GPS/network signal" on failure (4 locales)
2. Data update faked success on total failure:
   - updateFromRemote now counts successful sources; 0 success throws
     IOException -> timestamp NOT refreshed, Toast "Update failed -
     check your network" (4 locales, new IShowToast resId overload)
   - OkHttp timeouts widened: connect 15s / read 20s / write 20s

Verified: check_strings OK; all modules compile.
Release intentionally NOT triggered (user: fix everything first, then
one release).
