Pull Request Overview

This PR makes the description field optional and defaults mode to published for new nodes, and adds tests to verify creating metrics without explicitly providing those fields.

• Changed MutableNodeFields and CubeNodeFields so description is optional and added a default mode in MutableNodeFields.
• Introduced tests in metrics_test.py to ensure nodes can be created without description or mode.

• For consistency with MutableNodeFields, consider giving mode a default value here (e.g., mode: NodeMode = NodeMode.PUBLISHED).

    mode: NodeMode

• After asserting the status code, add checks for the response body to confirm mode defaults to 'published' and that description is handled (e.g., assert response.json()["mode"] == "published").

    assert response.status_code == 201
