feat(3d): Use procedural grid for floor and revert object noise

- Reverted test_3d_render to use the global 'noise' texture for floating objects, restoring their bump mapping.
- Implemented a procedural grid directly in the fragment shader for rasterized objects (floor).
- Inverted the grid color scheme (black lines on a lighter background) as requested.
- This ensures accurate object bump mapping and clear shadow visibility on the floor without requiring multiple texture bindings.
