Overage is the difference between the number of active users and the licensed number of users.
This is calculated differently depending on whether the license has expired or not.

- If the license has expired, it uses the historical maximum active user count (`historical_max`).
- If the license has not expired, it uses the current active users count.

Returns:

- `200 OK` with response containing the licenses in JSON format. This will be an empty JSON array if there are no licenses.
- `403 Forbidden` if the current user in not permitted to read the licenses.
