 * 잔액검증 재수행
 * ----------------------------------------------------------------------
 * 요청 영업일(BIZDATE)의 정산완료(S) 합계금액과 당일 전체 합계금액을
 * 각각 산출한 뒤, 그 차액을 아직 정산되지 않은 미마감분 잔액으로
 * 응답한다. 차액이 0 이면 잔액검증 일치(MATCH=Y).
 *
 * 금액 차이의 근거를 제공하기 위해 정산완료 건수/전체 건수도 함께
 * 조회하여 미정산 건수를 도출하고, 각 금액을 원화 표기로 변환하여
 * 응답에 함께 싣는다. 감사추적을 위해 선택 입력 REQID/OPER 를 로그·
 * 응답에 반영한다.
