Describe the issue
The ZUGFeRD Export should align with the XRechnung export
Expected behavior
If a "Company Bank Account" is set then the IBAN and Swift Code should come from the "Company Bank Account" instead of the company information.
Steps to reproduce
Create a Sales Invoice with "Company Bank Account" set.
Export this sales invoice.
