createTransaction now calls SobanleClient.createAutoOrder(customerData,
targetAmount, cb) before writing an AdminTransaction. The transaction's
amount is set from the real Sổ Bán Lẻ order total (order.orderTotal)
rather than the admin's raw input amount, and sobanleOrderId is stored
for reconciliation. On Sổ Bán Lẻ failure, returns 502
{code:"99", data:"SOBANLE_ORDER_FAILED"} with no DB row written. The
success response contract ({code:"00", data:{merTrxId, paymentUrl}}) is
unchanged.
