- Remove invalid null return from session callback (must return session object)
- Prevent admin from disabling their own account (guard with isSelf check)
- Hide disable UI when viewing own profile
- Add user existence check to changeDisabled endpoint
- Add OpenAPI metadata to changeDisabled mutation
