Fix lint errors in Phase 5 implementation

Frontend:
- CesiumGlobe.tsx: Remove unused Cesium imports (Entity, JulianDate, etc.)
- TimeControls.tsx: Remove unused addHours, subHours imports

Backend:
- tle_routes.py: Remove unused imports (TLESource, TLERecord, fetch_sample_satellites, delete, declarative_base)
