[Feature] Federated Authentication provider support

[bambamalicious]

Is your feature request related to a problem? Please describe. The ability to use federated authentication such as active directory would allow for SSO within networks.

Describe the solution you'd like Federated authentication support such as Entra ID or AD FS

I understand if its a big ask and doesn't get implemented, but it would be a nice facility to have for those using AD at home etc.

Adding on to this with some examples of other self-hosted auth strategies: Trusted Header and OIDC

Would love OIDC support

Other self-hosted python apps like tandoor have used django-allauth very effectively. I'm not familiar with the details of RomM's tech stack, but this could be a straightforward way to get OIDC.
