[FEATURE] Add groups support to the internal OIDC server

[graphixillusion]

Hi there. As the title says, is it possible to implement the groups managements to the internal OIDC server? For now this is only possible with external providers like pocketid.

Hi,

Would love this as a feature, i set up lldap to be able to use groups and came to the realization that i cannot use TOTP with those users, so currently there is no way to have both using Tinyauth. If there is a way to do this or perhaps a workaround i would love to hear it but i have not personally found one. Having group support for the internal users would be a great addition.
