Find a purchase invoice by external ID

Look up a single purchase invoice by its `external_id` (sent in the JSON body), the integration key that maps it to a record in a third-party system (ERP/CRM/e-commerce). Orthogonal to the supplier-provided `external_invoice_number` (the vendor's fiscal number). Returns the matching purchase invoice or 404 `purchase_invoice_not_found` if none uses that external_id within your company.
