Remove unused session state frames in Contest Analysis tab of app.py

- Deleted several session state frames ('stack_size_frame', 'general_frame', 'duplication_frame', 'ROI_frame') to streamline the state management in the Contest Analysis section.
- This cleanup enhances code clarity and reduces potential memory usage by ensuring only necessary frames are retained.
