Runs the full send flow on an invoice (same JSON as create_einvoice): VIES check of the buyer VAT, sanctions screen of the buyer name, EN 16931 create + validate, route lookup (Peppol/mandate), transport hand-off and an Ed25519-signed evidence receipt (JWS). transport: "mock" (simulated, default), "recommand" or "e-invoice-be" (the UBL is really submitted to that Peppol access point's sandbox, addressed to W System's own sandbox company; the partner document id is returned). Use it to build and test an integration before live sending exists.
