- expirePendingPastDeadline service: scans PENDING confirmations past
deadline, marks each EXPIRED + audit-logs, then promotes the next
waitlist entry per affected category (using each program's grand-final
round configJson for windowHours).
- /api/cron/finalist-confirmations: hourly cron entrypoint (CRON_SECRET
header gate), wraps the service.
- finalist.addToWaitlist: insert at a specific rank, shifting later
entries down (transactional).
- finalist.reorderWaitlist: rewrite a category's rank order in one go,
using a temp-rank trick to avoid unique-constraint conflicts mid-update.
- finalist.manualPromote: out-of-rank-order admin promote with audit log
(FINALIST_MANUAL_PROMOTE) + fresh confirmation email.
2 new tests. Suite at 14/14 for finalist-confirmation.
