Fix 3D scene loading issue

Problem: Scene stuck on loading screen
Cause: Texture loading blocking render + missing font file

Fixes:
- Temporarily disabled texture loading (useTexture)
- Temporarily disabled 3D dimension labels (Text component)
- Fallback to solid color materials
- Removed unused imports

Result: Scene loads immediately with procedural door geometry

Note: Textures and dimension labels can be re-enabled once:
1. Font file is added to public/fonts/
2. Texture preloading strategy is implemented
