Creates a party. Use partyType: INDIVIDUAL with firstName/lastName, or ORGANISATION with name (and optional vatNumber). The returned id is what you pass when opening an account. Identity verification runs asynchronously after creation — track it on kycStatus (individuals) or kybStatus (organisations); see Account verification.
