2024-04-10: Graph SDK for auth setup

We are now using msgraph-sdk instead of direct HTTP calls for our scripts that setup Entra application registrations. There should be no functional difference after the change.

What's Changed

• Bump pillow from 10.2.0 to 10.3.0 in /app/backend by @dependabot in #1486
• Port to the Graph SDK for authentication scripts by @pamelafox in #1510
