Update OpenCV dependency to headless version in requirements and setup files

- Replaced 'opencv-python' with 'opencv-python-headless' in both requirements.txt and setup.py to reduce unnecessary GUI dependencies.
- Added a new .gitkeep file in the logs directory to ensure it is tracked in version control.
- Maintained existing code logic while improving dependency management.
