Add level configuration system and update base station model

- Add level 1 JSON with 4 asteroids and difficulty config
- Add mission directory with recruit and fuel management missions
- Update base.glb model for space station
- Clean up unused helper functions in planetTextures.ts
- Refactor starBase.ts position handling to use container root node
