/**
 * `<SystemStatusSummary>` — compact at-a-glance system snapshot for the
 * `/admin` overview landing page.
 *
 * The full breakdown lives in `<SystemStatusSection>` at
 * `/admin/system-status`; this component only surfaces the handful of
 * facts an admin wants on the overview screen: app version, database
 * up/down, worker running, image build SHA + timestamp, and the
 * server-process start time. Same `useSystemStatus()` data source so we
 * don't re-fetch.
