[Worldline] Automatically add important payment gateway data (e.g. Payment ID, Refund ID, status updates) as order notes when WooCommerce custom fields are not present and the order is updated via webhook.

Why:

Some merchants have reported that their custom fields section is missing (likely due to theme or plugin conflicts), which prevents them from viewing important payment information such as PAYMENTID and refund tracking details.

This becomes problematic in cases where:

A payment is made, but the user doesn’t return to the site (webhook triggers the update).

Benefits:

Ensures merchants can still access vital payment/refund information, even if custom fields are unavailable.

Improves transparency and reduces confusion during support or reconciliation.
