📄 Description
When using trusted email header authentication, verify that the logged-in user's email matches the value in the header. This prevents session conflicts when the OAuth server changes the authenticated user.
Properly handle user session cleanup by deleting JWT and OAuth tokens on email mismatch
Verify trusted email header only after confirming user exists to avoid unnecessary checks
Only perform verification when WEBUI_AUTH_TRUSTED_EMAIL_HEADER is enabled
Force re-authentication with 401 error to ensure secure session transition
This change is important because:
It ensures proper session cleanup when the OAuth server changes the authenticated user
Prevents potential security issues where an old session could remain valid after user change
Maintains a consistent authentication state between the OAuth server and the application
Follows security best practices by immediately invalidating mismatched sessions
