[ECP-9547] Problem with Klarna PayOne

[Taran00]

Describe the bug
It seems that I cannot use Klarna PayNow as a payment method. The issue is caused by missing data (invoiceLines) required for the payment to be processed.

To Reproduce
Steps to reproduce the behavior:

1. Go to checkout and try to pay via Klarna PayNow
2. See error The Payment is Refused

Expected behavior
I should be redirected to the Klarna Gateway and able to complete the payment.

Magento version
2.4.6-p4

Plugin version
1.2.1

Additional context
I believe this payment method should work similarly to the default Klarna payment method. It seems that there’s a missing observer to add the correct BrandCode (similar to the BrandCodeDataAssigner). Without this, the required additional data for Klarna PayNow payments is not attached.

For test purposes, I have temporarily hardcoded the BrandCode value as 'klarna' during payment process, and with this modification, everything looks fine.
