perf(admin-web): reduce redundant polling and cover active publish status

Unify list/detail poll intervals to 5s and skip refetch while a query is
already in flight, replacing broad invalidateQueries cascades with targeted
refetches. Poll now also triggers on active publish status via the new
hasActivePublishStatus helper. Dedupe concurrent refreshBrands calls with a
shared promise and skip the redundant AppShell refresh when already
initialized. Gate publish-record loading on popover open.
