Fix file upload CORS issue for HF Spaces

- Add .streamlit/config.toml with proper server configuration
- Disable CORS and XSRF protection for HF Spaces compatibility
- Set maxUploadSize to 1024MB for large log files
- Update .gitignore to include .streamlit config
- Update Dockerfile to copy .streamlit directory

This fixes the axios 403 error when users upload files.
