Send a transactional email for an order (order_confirmation, invoice, etc.)

Sends a transactional email to the bill-to account’s primary contact with a PDF attachment of the order (invoice, quote, or purchase order depending on document_type). The PDF is generated on demand using the entity’s configured template. Email delivery is handled asynchronously via Postmark; delivery status can be tracked via the activity log. Requires orders:write scope.
