### What problem does this PR solve? Add `/login/channels` route and improve auth logic to support frontend integration with third-party login providers: - Add `/login/channels` route to provide authentication channel list with `display_name` and `icon` - Optimize user info parsing logic by prioritizing `avatar_url` and falling back to `picture` - Simplify OIDC token validation by removing unnecessary `kid` checks - Ensure `client_id` is safely cast to string during `audience` validation - Fix typo --- - Related pull request: #7379 ### Type of change - [x] New Feature (non-breaking change which adds functionality) - [x] Documentation Update
