OpenGL: Fix screenshot gray edge issue by correcting SetWindowPos usage

Browse Source 
- OpenGLSwapChain::Initialize now uses AdjustWindowRect before SetWindowPos
- This ensures window client area matches expected size (1280x720)
- Previously SetWindowPos was given client area size instead of full window size
- Removed debug fprintf statements from OpenGLDevice
- Updated minimal integration test to use cleaner code
