fix: revert AMSAT live data route; hardcode FM/Linear satellite lists

User decision: drop the AMSAT live-page fetch pipeline entirely (page
parsing, amateur whitelist, ISS module disambiguation, timeout fallbacks,
amSatListsVersion re-resolution) and hardcode the FM/Linear lists instead.

- Sources: remove amSatLiveUrls + amSatActiveUrls; add
  amSatFmCatnums = {SO-50 27607, ISS ZARYA 25544, AO-123 43137} and
  amSatLinearCatnums = {RS-44 44909, FO-29 24278, AO-7 7530,
  AO-73 39444, JO-97 43803}
- SelectionRepo: virtual types resolve FM/Linear from hardcoded sets;
  SSTV stays (amateur-only mode query + R/B debris exclusion)
- MutualViewModel: FM/Linear chips filter by the hardcoded sets
- DatabaseRepo/SettingsRepo/ISettingsRepo: AMSAT list fetch/persist
  removed; DataParser AMSAT parse helpers removed
- Tests: AMSAT pipeline tests dropped; selection/mutual tests re-targeted
  at the hardcoded lists
