fix(3d): Resolve shader validation error and tune shadows

- Fixed 'redefinition of light_dir' shader validation error by centralizing the light definition at the top of fs_main.
- Further brightened the floor in 'test_3d_render' for better shadow contrast.
- Reduced shadow bias and made the light more vertical to ensure shadows are clearly visible on all surfaces.
