Add support for Microsoft SSO

[angela-tran]

Microsoft is a common identity provider. Let's add usage of django-microsoft-sso to the admin interface.

Microsoft authentication seems to differ from Google in that it has the concept of tenants which narrows down the "universe" of users to the users that are a part of the tenant.

When configuring the library, we give it an application ID and client secret, both of which are associated with an application that is registered with a tenant.

For this task, we can test using an instance of Microsoft Entra ID using our Compiler Azure subscription. A separate task will cover setting up the production Microsoft Entra ID instance.

Acceptance Criteria

• Users in the test Microsoft Entra ID instance can log in to the admin interface
