fix(actions): adds loading guard for skeleton+stub render

ActionsTab groups Show lacked the loading guard that IssuesTab and
PullRequestsTab have. During initial load with locked repos,
ensureLockedRepoGroups injects stubs that made repoGroups().length > 0,
rendering stubs alongside the loading skeleton.
