New `schematron_validation_status` field on Customer Invoices

We've added a schematron_validation_status field to the Customer Invoice resource, so you can now check the outcome of Schematron structural validation for Factur-X invoices directly from the API.

New field: schematron_validation_status

Every Customer Invoice response now includes a schematron_validation_status field, right next to factur_x:

{
  "id": 123,
  "factur_x": true,
  "schematron_validation_status": "valid",
  ...
}

If you're importing Factur-X invoices through the API, you can poll schematron_validation_status to know whether an invoice is structurally valid before relying on it further downstream.
