 * Smoke test — exercise the re-price flow end-to-end.
 *
 *   1. Pick an existing quote with at least one quote_item.
 *   2. Snapshot the current state of N items.
 *   3. Set SKU on each item to a real catalogue row.
 *   4. Run the same matcher the endpoint uses (findFirstPriceListBySku),
 *      emulate the patch the endpoint would write.
 *   5. Restore the original values (so we don't leave the live DB
 *      in a half-baked state for the test).
 *
 * Run with:
 *   env PB_ADMIN_EMAIL=… PB_ADMIN_PASSWORD=… NEXT_PUBLIC_POCKETBASE_URL=…
