Fix container conflict errors - Force remove existing containers

- Force remove existing containers (ml_churn_api, mlflow_server) before deployment
- Use docker-compose down --remove-orphans to clean up properly
- Add cleanup step in Test Docker container to remove ml-api-test
- Stop and remove any containers using port 8000 before testing
- Prevents 'container name already in use' and 'port already allocated' errors
