 *
 * 마감 통계
 * ----------------------------------------------------------------------
 * 요청 영업일(BIZDATE)의 원장을 상태별로 각각 조회하여 미마감(R)/
 * 처리완료(M)/불일치(U)/정산완료(S) 4종 건수 통계를 산출한다. 4건의
 * 개별 count 조회 결과를 합산해 전체 건수와 정산 진척률(%, 정수)을
 * 계산한다.
 *
 * 금액 관점의 통계로 당일 전체 합계와 정산완료 합계를 추가 조회하여
 * 정산금액 비중(%)을 산출하고, 건수 기준 최다 상태(DOMINANT)를 판별해
 * 응답에 제공한다. 감사추적을 위해 선택 입력 REQID 를 반영한다.
