Keycloak configuration diverged from live servers

When starting keycloak from the repository with its default imported configuration, keycloak provides the following metadata to the REST API:
```json
{'exp': 1748938686, 'iat': 1748938386, 'jti': '40de1f44-41f7-477f-b1f1-3373bd381f6b', 'iss': 'http://localhost/aiod-auth/realms/aiod', 'aud': 'account', 'sub': '4a80f256-3928-4cfa-ba66-5e22bb36fc01', 'typ': 'Bearer', 'azp': 'aiod-api-swagger', 'session_state': 'db54b64f-8d55-4cd3-b3c7-d97cb27514c9', 'acr': '1', 'allowed-origins': ['http://localhost:8000/'], 'realm_access': {'roles': ['offline_access', 'uma_authorization', 'default-roles-aiod']}, 'resource_access': {'account': {'roles': ['manage-account', 'manage-account-links', 'view-profile']}}, 'scope': 'openid profile email', 'sid': 'db54b64f-8d55-4cd3-b3c7-d97cb27514c9', 'email_verified': False, 'preferred_username': 'user', 'given_name': '', 'family_name': '', 'client_id': 'aiod-api-swagger', 'username': 'user', 'token_type': 'Bearer', 'active': True}
```
But this is different form what the dev/prod keycloak servers provide. For example, there is no 'username' there. The configuration in the repository should match that in dev/prod w.r.t. roles, user metadata, and so on (though obviously not the users).
