 * cl_ol_0005.pgc - 마감 온라인 서비스 (CL_OL_0005)  [tier=medium]
 *
 * 마감 취소(재개방). 요청 영업일(BIZDATE)의 정산완료(S) 건을 처리완료(M)
 * 상태로 되돌려 마감을 재개방한다. 취소된 건수와 재개방 대상 금액합계를
 * 응답한다. 취소 대상(S 건)이 없으면 경고로 응답한다. (tx_begin/tx_commit)
 *
 * ── 서비스 계약(Contract) ────────────────────────────────────────────
 *  입력 필드:
 *    BIZDATE    (필수) 재개방 대상 영업일(YYYYMMDD)
 *  출력 필드:
 *    RESPCODE   0000=정상 / 9001=입력오류·대상없음 / 9999=시스템오류
 *    BIZDATE    처리 영업일
 *    CANCELCNT  취소(재개방)된 건수 (S→M)
 *    REOPENSUM  재개방 대상 금액합계(원)
 *
 * ── 상태전이 규칙 ────────────────────────────────────────────────────
 *    · 정산완료(S) 건만 취소 대상이며, 처리완료(M) 로 되돌린다.
 *    · 되돌린 M 건은 재마감(CL_OL_0006) 또는 마감확정(CL_OL_0016)의
 *      대상이 되어 다시 S 로 전이될 수 있다.
 *    · 취소 대상(S)이 0건이면 트랜잭션을 시작하지 않고 경고로 응답한다.
 *
 * ── 처리 흐름 ────────────────────────────────────────────────────────
 *    1) BIZDATE 추출/형식검증
 *    2) 취소 대상(S) 사전 건수/금액 집계 (0건이면 조기 반환)
 *    3) tx_begin → S→M 일괄 UPDATE → tx_commit
 *    4) 취소건수/금액 응답 구성
