/**
 * One-off data fix: corrects PaymentMethod.currency for methods whose settlement currency
 * was never set at seed time and silently defaulted to the schema's ETB default.
 *
 * payments.service.ts's chargeCurrency resolution reads this column directly (see the
 * comment above `chargeCurrency` in `initiatePayment`): WAAFI settles in DJF, CARD in USD.
 * With WAAFI stuck on the ETB default, live Waafi payments were charged in ETB instead of
 * being converted to DJF — not just a mislabeled report. This script only touches the
 * PaymentMethod config row; it does NOT rewrite any existing PaymentIntent/Booking records,
 * since correcting historical transaction currency is a financial decision, not a data-fix
 * this script should make unilaterally.
 *
 * Safe to re-run. Only updates rows that already exist; does not create new ones.
 *
 * Usage: node --env-file=.env -r ts-node/register prisma/fix-payment-method-currency.ts
