- Changed backend port from 809 to 901 (9xx range for backends)
- Updated docker-compose.yml to expose backend on port 901
- Created new Caddyfile with files.mad-lawsuit.org subdomain
- Simplified mad-lawsuit.org to only proxy to frontend (port 806)
- Updated frontend API proxy to use https://files.mad-lawsuit.org
- Updated backend CORS to allow both mad-lawsuit.org and files.mad-lawsuit.org
- This fixes PDF download reliability issues by providing direct backend access
