Keep skeleton up while moderation labels are still resolving

useFeaturedOrganizations is internally gated on moderationReady — while
the organization moderation labels are loading, the underlying query
is disabled and reports isLoading: false / data: undefined. The Groups
page was using only that isLoading flag to decide whether to show the
skeleton, so during the moderation-loading window it rendered the
empty state for a moment before the curated grid popped in.

Track moderation readiness alongside the featured query and treat any
of the three states — moderation not ready, featured query in flight,
featured data not yet defined — as loading.
