Use new laravel SCIM server

[uberbrady]

This isn't done yet. But it's an attempt to pull us up to a newer version of the laravel-scim-server library - or, at least, our fork of it, which is modified to provider slightly better logging.

It includes Group support. It will dynamically create groups according to which groups you have assigned to you as the service-provider side. Those groups inherently will have no permissions; the administrator needs to associate whichever permissions they want to whatever groups that are dynamically created. I'm not sure what will happen if the SCIM client (the Identity Provider) tries to assign a currently-existing group to a user - I imagine it will just grab that group by name and assign it.

I've been able to re-add Manager support. And it will understand Azure/Entra ID's messed-up violates-the-spec version of it. As well as standards-compliant versions of it, once that's implemented (it hasn't been, yet).

I've implemented Location and Company support as well. These have to be mapped to custom SCIM attributes -

• urn:ietf:params:scim:schemas:extension:grokability:2.0:User:location
• urn:ietf:params:scim:schemas:extension:grokability:2.0:User:company

These will actually create locations and companies if they don't exist. If you don't want that behavior, don't map those attributes.

I've tested it pretty heavily against Entra ID, but I need to keep testing it there, as well as a few other providers before it's ready for the world. Also some functionality still needs to be fleshed out and/or cleaned up.

But, it's progress.
