Reduce debounce time for window resize updates and improve window size handling

- Lowered debounce time from 100ms to 10ms in `ImageInfoWindow` for both MacOS and Win32, enabling faster resize updates.
- Fixed width and height assignment logic in `WindowFunctions` for consistent behavior.
- Added debug logging for invalid width and height values in `InitializeWindowSizeAndPosition`.
