The third_party:/opt/apps volume was accidentally uncommented in
docker-compose.yml. Without submodules checked out, this empty mount
breaks the Notes app installation hook in CI.
Fix: keep the mount commented in docker-compose.yml and add a separate
docker-compose.oidc.yml override that's only used for OIDC-requiring
profiles (oauth, login-flow) in CI.
