[feat](trx-rs): add ham sat pass predictions; rename SAT tab

- Rename "Weather Satellites" sub-tab to "SAT"
- Add "Predictions" view: next 24 h flyby table for 13 ham sats
  (ISS, AO-91, AO-92, SO-50, AO-73, JO-97, PO-101, LilacSat-2,
  CAS-4B, EO-88, RS-44, SALSAT, GREENCUBE)
- trx-core/geo: add PassPrediction, HAM_SATS, compute_upcoming_passes(),
  find_passes_for_sat(), compute_az_el() helpers; spawn_tle_refresh_task
  now also fetches CelesTrak amateur group on startup and every 24 h
- trx-frontend-http: add GET /sat_passes endpoint
- app.js: locator tooltips now accumulate all receivers per station
  via remotes Set; _detailPassesRigFilter checks the Set
