feat(tgu-ops-ui): display real ground track and swath from ballistics service

Replace synthetic orbit calculation (Kepler + spacecraft ID hash) with real
data from pcp-ballistics-service via a new proxy endpoint in pcp-ui-service.

Backend:
- TguPlanningController: add GET /api/tgu-planning/spacecraft/{noradId}/flight-line
  that proxies FlightLineDTO[] from BallisticsService for a given time interval

Frontend:
- Fetch FlightLineDTO[] (revolution, time, lat/long, swath boundaries) using
  the spacecraft's noradId for the current 24h map window
- Group points by real revolution number to build OrbitPassInfo[] with actual
  orbit numbers and UTC times instead of synthetic Kepler-based estimates
- Build ground track MapLines and swath MapPolygons from real coordinates;
  swath polygon = outer-left edge forward + outer-right edge reversed
- Enable swath layer in the editor map; draw with teal fill/stroke matching
  the track colour
- MapPassSelector now shows real revolution numbers in header and handle labels
