Subject: [PATCH] Implement request handling for 3D models in app.js

- Added middleware to prevent direct access to /models/ paths, directing users to use /api/models/ instead for optimized 3D models.
- Updated comments to clarify the purpose of the new middleware and its role in serving models through the API.
