fix(gpu): Resolve high-DPI squished rendering and 3D shadow bugs

- Implemented dynamic resolution support in all shaders and effects.
- Added explicit viewport setting for all render passes to ensure correct scaling.
- Fixed 3D shadow mapping by adding PLANE support and standardizing soft shadow logic.
- Propagated resize events through the Effect hierarchy.
- Applied project-wide code formatting.
