Pull request overview

This PR refactors the transparent mode setup logic to consolidate two separate methods (SetupOutline and SetupOverDrawTransparentObject) into a single parameterized method (SetupTransparentMode). This reduces code duplication and improves maintainability by centralizing the logic for handling transparent vs non-transparent rendering modes.

Key Changes

• Consolidated SetupOutline and SetupOverDrawTransparentObject into a single SetupTransparentMode method
• Updated call sites in both UTS3GUI.cs and BuiltInUTS2toIntegratedConverter.cs to use the new unified method

The constant name srpDefaultCullMode contains 'Col' which appears to be a typo for 'Cull'. This should be renamed to _SRPDefaultUnlitCullMode for clarity and consistency with Unity naming conventions.
