* chore: update API endpoints to support default JWT auth
The default DRF Auth classes were recently updated to allow for both JWT and Session auth by default. Any endpoint that overrides the AUTHENTICATION_CLASSES but has just session, just JWT or just both of those should be updated to remove the override.

Fix all deprecation warnings generated by Django REST Framework during the unit tests:
* ``The `base_name` argument is pending deprecation in favor of `basename`.`` (86 occurrences)
* `` `detail_route` is deprecated and will be removed in 3.10 in favor of `action`, which accepts a `detail` bool. Use `@action(detail=True)` instead.`` (18 occurrences)
