differenceInDays truncates to whole days, so an event expiring in a few
hours returned 0 and three admin surfaces treated it as gone:
- EventsListPage: status chip said 'Expired' (days <= 0) while the
public gallery — which compares real timestamps — correctly showed
'expires in X hours'. This is the reporter's exact symptom.
- EventDetailsPage: same isExpired math on the detail view.
- AdminDashboard: the expiring-soon card showed '0 days left' on the
final day.
Expired is now gated on the actual timestamp (expires_at <= now), and
the countdown chips use ceiling days so the last day reads '1 day
left' instead of flipping to Expired/0.
