 *
 * One-shot data-fix for the Kusasalethu PO 390588 invoice INV10924
 * incident. The driver collected 8 of one line and 7 of another (15
 * total), but the QuickBooks invoice billed 10 of each (20 total) — 5
 * units were over-billed. This script back-fills PB so the row state
 * agrees with reality:
 *
 *   - `quantity` on each line is dropped to match what was collected
 *     (10 → 8 on the 0161HDAKWF line, 10 → 7 on the 2161HDAKWF line).
 *     Without this, `quantity - qty_collected` stays positive and the
 *     new "outstanding qty" badge would mis-report the shortfall.
 *
 *   - `qty_invoiced` is stamped on both rows (= qty_collected).
 *
 *   - `customer_invoice_number` and `invoiced_date` are stamped so
 *     the operator-facing pages cite INV10924 instead of showing a
 *     blank.
 *
 *   - `item_status` flips to "invoiced" (matching what the operator
 *     sees in QuickBooks) so the rows drop off the to-invoice tab.
 *     The order's `invoiced` flag is also flipped to true.
 *
 * QuickBooks itself is NOT touched — leaving INV10924 as-is and
 * raising a follow-up invoice once the supplier delivers the rest is
 * the agreed remediation. If you'd rather credit-note 5 units, do
 * that in QuickBooks manually and tell me the credit-memo number so
 * I can stamp `customer_credit_number` (would need a schema add).
 *
 * Usage:
 *   npx tsx scripts/nss-fix-kusasalethu-inv10924.ts
 *
 * Requires PB_ADMIN_EMAIL / PB_ADMIN_PASSWORD in .env.local (already
 * present in this repo).
