Create mesh-based physics for ship and optimize planet geometry

- Update Ship class to use CONVEX_HULL physics from ship1.glb
  - Find geometry mesh from loaded GLB and create physics from it
  - Move physics creation to initialize() after mesh loads
  - Add fallback to BOX shape if mesh not found

- Fix ship position setter for async initialization
  - Add null check for physics body
  - Set transform position directly if body doesn't exist yet
  - Prevents crash when position set before mesh loads

- Optimize planet vertex count for performance
  - Reduce sphere segments from 32 to 12
  - ~144 vertices vs ~1024 vertices per planet
  - Planets are background objects, lower poly acceptable

- Update ship1.glb model
