paypalOrderId is the PayPal order the checkout created for the order, paypalCaptureId and paymentCapturedAt record the verified capture. All three are private, so the content API never returns them. Strapi adds the columns when it syncs the schema at startup. types/generated/contentTypes.d.ts is the output of strapi ts:generate-types, run in the release image without network. Refs libretech/mp#71
