Klarna (Klarna One) with setting API method payment is not working

[DerKaito]

Hello,

I currently found the issue that with the Klarna payment method is not working with the Payment API Setting.
This is intended as Klarna needs the complete cart, but Klarna is missing in the list of onlyOrders Methods in the isPaymentsApiAllowed function.

Shopware/Components/Constants/PaymentMethodType.php

Lines 30 to 38 in 6571f47

	$onlyOrders = [
	PaymentMethod::KLARNA_PAY_LATER,
	PaymentMethod::KLARNA_PAY_NOW,
	PaymentMethod::KLARNA_SLICE_IT,
	$prefix . PaymentMethod::KLARNA_PAY_LATER,
	$prefix . PaymentMethod::KLARNA_PAY_NOW,
	$prefix . PaymentMethod::KLARNA_SLICE_IT,
	# ----------------------------------------------------------
	PaymentMethod::VOUCHERS,

The Klarna payment Methods in the list are the Klarna options not the unified Klarna Method

Hi @DerKaito thanks for your contribution! Please keep in mind that using Klarna over the payments API has implications for backend processes like reconciliation - you should check the reports for changed descriptions. Klarna payments will also now show up in the "payments" tab of your Mollie dashboard, not in "orders" anymore.

@hreinberger The Payment method doesn't implement the payments API.

Shopware/Services/Mollie/Payments/Requests/Klarna.php

Line 32 in 6571f47

throw new ApiNotSupportedException('Klarna One does not support the Payments API!');

That is why I fixed it in my PR #449 by restoring the old behavior that Klarna uses the Order API. Less plugin rewrite and so on.
From my understanding in that case all stays the way it was. Still having Klarna in the Order Tab right?
