\Affirm\Telesales\Block\Adminhtml\Order\View::getReadCheckoutAPI calls undefined method

[pkarsai]

There is an error in \Affirm\Telesales\Block\Adminhtml\Order\View::getReadCheckoutAPI, in line 268. $readCheckoutResponse is of type \Laminas\Http\Response, which doesn't have a getMessage method (and neither do its ancestors).

This leads to some orders failing to display in the admin order view if they happen to trigger this error branch (status > 200).
