/**
 * Adds a "Payment Method" entry to the order summary sidebar — previously
 * nowhere on the order page told staff which payment method a shopper
 * actually used. Reads Order.meta['payment_method'] (written by
 * Modules\Core\Checkout\Services\CheckoutService::initiatePayment()), the
 * same source Modules\Core\Order\Services\OrderStatusFlow::isCod() reads,
 * so this entry and the "Mark Paid" action's visibility always agree on
 * what payment method an order used. Falls back to the most recent
 * Transaction.driver for an order placed before that field existed.
 *
 * Uses the extendOrderSummarySchema hook, same as the deleted 3-axis
 * OrderStatusSummaryExtension did — see that class's git history for the
 * hook's own docblock/rationale.
