[azure] Bug fix + test cleanup

[agulen]

Overview

Jira

I noticed a bug in my last PR where subscription ID and name were being returned in an array together in the JSON payload reported to the front end. These should not be in an array like this.

This is because these 2 values were previously stored in a dict[str,str] where id -> name, but were updated to a tuple[str,str]. Python converts tuples into lists during JSON encoding.

I updated the LfoControlPlane dataclass to have 2 explicit properties for sub_id and sub_name to avoid any confusion.

I also took some time to refactor + clean up a bunch of tests. I centralized a bunch of shared test data into test_data.py, further differentiated subscription IDs and subscription names in test data, and updated individual tests accordingly.

Testing

• Unit tests passing
• Manual test looks good
