fix: use real SatNOGS TLE source so newly launched satellites appear

- Point the built-in SatNOGS source at db.satnogs.org/api/tle/?format=3le
  (the CelesTrak satnogs group is a separate, slower subset); rename the
  old CelesTrak source to 'CelesTrak SatNOGS'.
- Add a one-time migration in SettingsRepo: installed apps that already
  persisted a satelliteUrls list containing the old CelesTrak SatNOGS URL
  get the real SatNOGS TLE URL inserted right after it.
- Dedupe imported satellites by catnum and radios by uuid in
  DatabaseRepo.updateFromRemote so multiple sources don't insert the
  same primary key twice.
- Test: importing JAMX-0825b (NORAD 98248) from the real SatNOGS source.
