fix: correct AMSAT live filter satellite lists

- Resolve ISS station modules (ZARYA/UNITY/ZVEZDA/DESTINY/NAUKA) to the
  primary 25544 instead of whichever module appears first in the TLE source
- Match OSCAR designators to local names spelled 'OSCAR N'/'AMSAT-OSCAR N'
  (AO-7 -> OSCAR 7) so Linear lists keep AO-7 on SatNOGS-sourced data
- SSTV virtual type now uses the transceiver service class (Amateur only)
  plus launcher-debris name exclusion, dropping retired weather birds
  (TIROS) and rocket bodies (ARIANE 6 R/B) while keeping ISS/CSS/TEIKYOSAT
- Persist the AMSAT active-frequency whitelist (palewire mirror) on sync;
  used only to disambiguate multi-match names, never as a hard filter
