Executes a Card Account (CA) transfer-out based on a locked FX quote. This transaction incurs zero service fees.

• Prerequisite: You must first obtain a quoteId via GET /open-api/v1/transfer/ca-transfer-out/fx-quote.
• Idempotency: The quoteId acts as the idempotency key and can only be consumed once.
• Supported Transfers: Funds can be moved to a VA group (ca_2_va, USD allowed) or a Crypto Wallet (ca_2_cw, USD strictly prohibited).
• Routing: The source balance (fromBalanceId, CA master in USD) is automatically resolved by the server.
• Restrictions: Frozen accounts and PSP customers are not supported. Corporate users may be subject to OTC quota limits unless explicitly whitelisted.
• Note: For instant Card Account to Crypto Wallet transfers, use POST /crypto-wallet/transfer.
