Modularized lighting calculations by introducing DefaultSetup.hlsl and Lambert.hlsl includes, and updated BlendinShader, LitParticles, and Water shaders to use these macros. Added new wave-related properties and logic to Water.shader for enhanced wave effects. Improved maintainability and consistency across shaders by centralizing light and Lambertian diffuse calculations.
