Find an expense by external ID
Look up a single expense 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 expense or 404 purchase_invoice_not_found if none uses that external_id within your company.
