The existing `global.appConfig.gitlab_kas.enabled: false` only affected the KAS subchart config but was ignored by the chart template that generates gitlab.yml. Adding `global.kas.enabled: false` properly sets `gitlab_kas.enabled: false` in gitlab.yml and removes the orphaned gitlab-kas Service, stopping ~5 GRPC::Unavailable errors per git push.
