 * 스냅샷 조회
 * ----------------------------------------------------------------------
 * 요청 영업일(BIZDATE)의 마감 스냅샷 요약행을 key=BIZDATE+"SS" 로 표준
 * DBIO(cl_rec_select) 를 통해 조회한다. 스냅샷 요약행은 마감 시점의
 * 합계(amount)/건수(fee) 를 담고 있으며, 없으면 스냅샷 미생성으로 보아
 * ENOENT(FOUND=N) 를 응답한다.
 *
 * 스냅샷이 존재하면 현재 원장의 실집계(합계/건수)를 재산출하여 스냅샷
 * 시점 대비 변동분(DRIFT)을 함께 제공한다. 변동이 0 이면 스냅샷과
 * 현행이 일치(FRESH=Y). 감사추적을 위해 선택 입력 REQID 를 반영한다.
