[feat](trx-rs): add weather satellite map overlay integration

Add SGP4-based geo-referencing for NOAA APT and Meteor LRPT decoded
satellite images, enabling them to be displayed as semi-transparent
overlays on the Leaflet map module with ground track polylines.

Changes:
- Add sgp4 crate dependency to trx-core for orbital propagation
- New trx-core/src/geo.rs module with TLE-based pass geo-referencing,
  ECI-to-geodetic conversion, and station-location fallback estimation
- Extend WxsatImage and LrptImage structs with geo_bounds and
  ground_track optional fields (backward compatible via serde defaults)
- Compute geo-bounds in finalize_wxsat_pass and finalize_lrpt_pass
  using satellite identity, pass timestamps, and station coordinates
- Add 'wxsat' source filter to the map module (off by default)
- Add L.imageOverlay rendering with popup and ground track polyline
- Add "Show on Map" buttons in wxsat plugin live/history views
