/**
 * Periodic ticket auto-close (server/utils/ticketAutoClose.ts): tickets waiting on the
 * merchant (IsMerchantAction) without activity for TICKET_AUTOCLOSE_DAYS (default 10)
 * are closed, annotated in the chat history and the merchant is mailed.
 * Mirrors listing-outbox-flush.ts (no Nitro cron infra here).
 *
 * Env: TICKET_AUTOCLOSE_ENABLED — default ON only in production builds; a dev server
 *      runs against the PROD iDempiere, so it must opt in explicitly with =1.
 *      TICKET_AUTOCLOSE_DAYS (default 10), TICKET_AUTOCLOSE_INTERVAL_MS (default 6 h),
 *      TICKET_AUTOCLOSE_DRY_RUN=1 logs what would be closed without writing / mailing.
 * Only PM2 instance 0 runs it (NODE_APP_INSTANCE) so a cluster never double-closes.
 * Manual / verification run: POST /api/requests/requests/auto-close { dryRun, days }.
