Revolut API Request

1. Use RevolutClient (wrapper over Http::withHeaders(...))
2. Always send Revolut-Api-Version header
3. Base URL: sandbox https://sandbox-merchant.revolut.com/api / prod https://merchant.revolut.com/api
4. Authorization: Authorization: Bearer {api_key}
5. Map responses through Response DTO → Support DTO
6. Check the operation's markdown spec before sending a field: https://developer.revolut.com/docs/api/merchant/operations/<operation>.md (curl + browser User-Agent). A field the spec does not list is ignored by Revolut — the data is dropped silently and the code still looks like it works.
7. Idempotency-Key is honoured on the refund, the subscription create and usage records only. Orders and payments accept no key; a charge is deduplicated via merchant_order_data.reference + GET /orders?merchant_order_data_reference=.
