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

-### Track satellite passes with ease!
+## 上游仓库
 
-Thanks to [Celestrak](https://celestrak.com/) and [SatNOGS](https://satnogs.org/) you have access to over 9000 active satellites.\
-You can search the entire database by NORAD Catalog Number or the satellite's name.
+本仓库是 [rt-bishop/Look4Sat](https://github.com/rt-bishop/Look4Sat) 的分支，上游仓库的原始功能包括：
 
-Orbital positions and passes are calculated relative to your location.\
-To get reliable data make sure to set the station position via the app Settings.
+- 基于 Celestrak / SatNOGS 数据的 9000+ 活跃卫星追踪
+- SGP4/SDP4 轨道预测，10 天过境预报
+- 极坐标雷达图、地面轨迹图
+- SSTV 图像解码
+- 无广告、无跟踪、完全离线
 
-The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.\
-It is now and always will be completely ad-free and open-source.
+## 许可证
 
-## Main features:
-
-*  Predicting satellite positions and passes for up to 10 days
-*  Showing the list of currently active and upcoming satellite passes
-*  Showing the active pass progress, polar trajectory and transceivers info
-*  Showing the satellite positional data, footprint and ground track on the map
-*  Custom TLE satellite data import is available via Three Line Element .txt files
-*  Offline first: calculations are made offline. Weekly TLE data update is recommended.
