Fix Docker Compose cache issue with proper cleanup

- Use docker-compose down to clear old service definitions
- Use docker system prune -f to remove cached metadata
- Verify new compose file is deployed correctly
- Force rebuild with --build flag
- This ensures new nginx-only config is used instead of cached old stack
