Refunds are now processed automatically. If the automated processing fails, the system falls back to the previous behavior of notifying the Support Team. Additionally, these calls are all made by the service user rather than the learner.

We should not be using custom signing keys for each service at this time. We may want to return to this strategy in the future; but, this is not the direction any of our other services are going in.

Updating commerce api endpoint to capture user UTM cookies and resend them in the server request to the ecommerce IDA.
Currently, the non-free purchases are tracked because the user makes the request directly on ecommerce and user cookie
contains UTM data, but for free purchases, the UTM cookie isn't sent in the background server request to the ecommerce
IDA.
