Task 573: Use Epoch-Derived Planet Positions in 3D Viewer

Status: DONE

Description

The 3D full-route viewer uses hard-coded planet angles (Mars ~18°, Jupiter ~63°, etc.)

instead of actual ecliptic longitudes from the mission epoch. This makes the 3D

visualization inconsistent with the 2D SVG diagrams (which use ephemeris-derived angles).

Plan

1. Add eclipticLongitudeRad to ZHeightAnalysis in orbital-3d-analysis.ts
2. Regenerate 3d_orbital_analysis.json with longitude data
3. Update prepareFullRouteScene() in orbital-3d-viewer-data.ts to use longitudes
4. Update inline JS in templates.ts and standalone orbital-3d.html
5. Add/update tests
