refactor: clean up unused imports and streamline useControls in basic components

- Removed unused imports such as BasicShadowMap, NoToneMapping, and SRGBColorSpace from Primitives.vue and PrimitivesModel.vue to enhance code clarity.
- Updated the useControls destructuring in index.vue to remove the alpha property, simplifying the control setup for better maintainability.
