[BUG] OIDC_ADMIN_CLAIM setting is not honored

Pre-flight checklist

• I have searched existing issues and this bug has not been reported yet
• I am running the latest available version of TREK
• I have read the Troubleshooting guide and my issue is not covered there

TREK version

4.2.1

Describe the bug

I have set up Authentik as my OIDC provider. I have created a custom entitlement called "trek-admins". I updated my Docker compose and set OIDC_ADMIN_CLAIM=entitlements and OIDC_ADMIN_VALUE=trek-admins. On my next login, my user (the only admin user) had its admin permissions removed. Setting OIDC_ADMIN_CLAIM=groups and OIDC_ADMIN_VALUE=authentik Admins resolves the issue and adds my account back to being an admin.

Steps to reproduce

1. Configure OIDC_ADMIN_CLAIM to be anything other than groups.
2. Make sure your user is transmitting whatever claim you are matching on.
3. Log in to Trek and you will no longer be an admin.

Expected behavior

I expect Trek to honor the OIDC_ADMIN_CLAIM value.
