fix: correct RioPay API header case and remove undocumented fields

Header was 'x-api-token' but RioPay API expects 'X-Api-Token'
(case-sensitive check on their side), causing 403 Invalid API token.

Also removed undocumented 'currency' and 'failUrl' fields from
create_order payload per official RioPay API docs.
