/***********************************************************************************************************************************************************************
 * File Name    : expire_advertisements.cron.js
 * Type         : Cron Job
 * Description  : Auto-archives (soft-deletes) advertisements once their
 *                end_date has passed, so expired ads don't sit indefinitely
 *                in the active Advertisements list — they fall through to
 *                the Archived Advertisements table, same path as a manual
 *                archive action.
 *
 *                Only touches rows with end_date IS NOT NULL so ads with no
 *                end date (run indefinitely) are never auto-archived.
 *
 * Schedule     : Every minute ("* * * * *"). Registered by cron/client.cron.js.
