Update all edx-platform REST endpoints to support JWT Auth

[feanil]

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.

Related Issue: #33302

Tasks

• Update all API views that explicitly accept only SessionAuth to use the DEFAULT_AUTHENTICATION_CLASSES instead.

Acceptance Criteria

• There are no API Views in edx-platform that explicitly only allow SessionAuth, only JWT Auth, or only those two together.
• It's fine to break this up into multiple PRs to ease review and land smaller changes.
