 * File Name    : fail_stale_payments.cron.js
 * Type         : Cron Job
 * Description  : Marks abandoned checkout attempts as 'failed' instead of
 *                leaving them stuck on 'pending' forever.
 *
 *                A payment/purchase row is created as 'pending' the moment
 *                PayPal's create-order call succeeds (createOrder / createCourseOrder),
 *                before the buyer ever reaches PayPal's approval page. If PayPal's
 *                own hosted checkout then fails to load ("Things don't appear to
 *                be working at the moment") or the buyer just abandons the tab,
 *                the browser never gets redirected back to our return_url/cancel_url —
 *                so captureOrder/cancelOrder is never called, and the row sits as
 *                'pending' indefinitely even though no money ever moved.
 *
 *                This job sweeps 'pending' rows older than STALE_MINUTES and
 *                marks them 'failed', so payment history correctly reflects
 *                that nothing was charged, instead of silently doing nothing.
 *
 * Schedule     : Every 10 minutes ("*\/10 * * * *"). Registered by cron/client.cron.js.
