Add project configuration and scene controller

- Created a new project configuration file `project.json` with metadata, camera settings, scene details, and lighting configurations.
- Implemented a new scene controller in `scena-controller copy.js` to manage 3D scene rendering, model loading, and user interactions.
- Integrated various loaders for STL and GLB models, along with functionality for dynamic material updates and model visibility toggling.
- Enhanced camera controls using TrackballControls for improved user navigation within the 3D environment.
