Implement ultra-high DPI plots and fix UI responsiveness

- Upgraded to DPI 1200 for ultra-sharp 14,400x8,400px images
- Fixed UI lag by restoring proper Streamlit rerun flow
- User messages now appear in blue immediately
- Plots will now match test_image.py quality standards
- Optimized font sizes for better readability at high DPI
