fix(3d): Correct debug box transforms and restore object textures

- Updated VisualDebug to accept mat4 transforms, enabling wireframes to follow rotating objects.
- Restored SDF bump mapping and floor grid texture in the fragment shader.
- Added vec4::xyz() helper to mini_math.h.
- Fixed Renderer3D to pass the full model matrix for debug visualization.
