Allow Latvian (LV) companies to register to Peppol

This change allows Latvian (LV) companies to register to receive Peppol invoices. To be eligible, the company must be registered in Maventa with a valid LV:VAT business identifier.

As with other countries, use the POST /v1/company/profiles endpoint to register your Latvian company to Peppol.

Example request payload:

{
  "profiles": [
    "INVOICE_AND_CREDIT_NOTE"
  ],
  "network": "PEPPOL"
}
