주문번호 R로 POST /orders 전송
 ├─ 201 또는 200 → order_id를 저장합니다. 끝.
 ├─ 400 items / balance / risk → 주문이 생성되지 않았습니다.
 │      원인을 해결하고 다시 보냅니다. R을 그대로 써도 됩니다.
 ├─ 400 external_order_id → R은 다른 주문에 쓰인 번호입니다. 멈추고 확인하세요.
 ├─ 403 서명 오류 → 다시 서명해서 같은 본문을 보냅니다.
 ├─ 429 → Retry-After만큼 기다린 뒤 다시 서명해서 같은 본문을 보냅니다.
 └─ 타임아웃, 5xx, 연결 끊김
        → 같은 R로 같은 본문을 다시 보냅니다.
          201이면 첫 요청이 도착하지 않은 것이고, 200이면 도착했던 것입니다.
