 * rc_ol_0018.pgc - 대사 통계 조회 온라인 서비스 (RC_OL_0018)
 *
 * 지정 영업일(BIZDATE)의 원장 전체를 커서로 순회하며 대사 통계를 집계한다.
 *
 * [집계 항목]
 *   CNT       - 대상 건수
 *   MINAMT    - 최소 거래금액
 *   MAXAMT    - 최대 거래금액
 *   SUMAMT    - 거래금액 합계
 *   AVGAMT    - 평균 거래금액 (SUMAMT / CNT, 0 나눗셈 방지)
 *   MATCHRATE - 대사완료율 (matched * 100 / CNT)
 *
 * [대사완료 판정]
 *   상태가 매입확정('M') 또는 정산완료('S') 인 건을 대사완료로 본다.
 *   접수('R')/불일치('U') 는 미완료로 집계된다.
 *
 * 원장을 변경하지 않는 순수 조회(read-only) 서비스이며, 커서 기반이므로
 * txcore_dbio.h 의 TX_SQL_OK / TX_SQL_NOTFOUND / TX_DBIO_LOG_ERR 를 사용한다.
