fix: authn login in dev by disabling enterprise integration

In development, login via the authn mfe was broken because of explicit
enterprise integration:

    requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=18000): Max retries exceeded with url: /enterprise/api/v1/enterprise-learner/?username=regis (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fd4c02b8a90>: Failed to establish a new connection: [Errno 111] Connection refused'))
