Fix build issues: csproj references, Unity modules, Harmony calls

- Fixed csproj to reference all Unity modules (Core, Audio, IMG, Input, TextRendering, UI)
- Fixed AudioMixerGUI namespace conflicts (GUI.Window vs UnityEngine.GUI.Window)
- Fixed Harmony UnpatchAll -> UnpatchSelf
- Removed duplicate AssemblyInfo.cs
- Build now succeeds and DLL deployed to BepInEx/plugins
