Problem:
When using Casdoor as an OpenID provider, there's an inconsistency between the user information in the JWT token and the UserInfo endpoint. The token contains the user's unique ID in the `name` field, while the UserInfo endpoint correctly returns the user's display name.
Solution:
This PR adds a new `ForceUserInfo` option to the OpenID provider configuration. When enabled, it forces the use of the UserInfo endpoint to retrieve user information instead of relying on claims from the ID token.
Impact:
- Default behavior remains unchanged (backward compatible)
- New option allows administrators to force using UserInfo endpoint data
- Particularly useful for providers like Casdoor that don't fully comply with OIDC standards

I've opened an issue in the Casdoor repository (https://github.com/casdoor/casdoor/issues/3806) to discuss the root cause. However, changing Casdoor's token structure might cause significant compatibility issues for existing integrations, so it's unclear if this can be fixed at the provider level. This PR provides a workaround in Vikunja that doesn't affect existing functionality.
This improves the UX because it does not allow external users to change their name in Vikunja, since that change would be overridden once they log in again.
Resolves https://github.com/go-vikunja/vikunja/issues/357
The config values for openid providers now use a map with the provider as key instead of an array. For example before:
auth:
openid:
providers:
- name: foo
clientid: ...
now becomes:
auth:
openid:
providers:
foo:
clientid: ...
This allows us to read values for openid providers from files using the same syntax as everywhere and makes the configuration more predictable. It also allows configuring providers through env variables, though it is still required to set at least one value via the config file because Vikunja won't discover the provider otherwise.
This PR fixes an issue discussed in #2152. Before this PR, the user who triggered team creation automatically got the admin flag set for this group, which makes perfect sense for the normal UI workflow. OIDC managed teams cannot be edited in Vikunja, and they're created automatically by the first user logging in having this team assigned. This PR therefore makes sure that OIDC managed team members do not receive the admin flag.
