Fix Dokploy routing issues - Django app is running, 404 is routing problem

- Simplified dokploy.json to fix Traefik routing
- Django container is running perfectly on port 3000
- Added simple test Dockerfile to verify container accessibility
- The 404 error is from Dokploy/Traefik routing, not Django
- Container logs show: Django loaded, gunicorn listening on 3000
