fix(ACDC): hide Processor Response row for approved orders on edit order page (6429)

[Narek13]

Description

On the WooCommerce edit order page, ACDC orders were showing a "Processor Response: 0000: Approved" row in the order totals section. Code 0000 means the payment was approved — there is nothing actionable for the merchant, so the row should not be displayed.

The display is rendered by a hook in WCGatewayModule that only checked empty($fraud_result['response_code']). Since '0000' is non-empty, it passed the guard and was always printed for ACDC orders. The fix adds || $fraud_result['response_code'] === '0000' to the early-return condition, suppressing the row for approved payments. Non-0000 codes (declines, errors, etc.) continue to display as before.

A functional test assertion was added to WooCommerceOrderEdit.assertOrderDetails to verify the row is absent for all ACDC orders going forward.

Steps to Test

1. Enable ACDC (Advanced Card Processing) in the plugin settings.
2. Complete a checkout using a test card (e.g. the default Visa test card).
3. Navigate to WooCommerce → Orders and open the newly created order.
4. Confirm the "Processor Response" row is no longer visible in the order totals section beneath the PayPal Payout line.
