 * rc_bt_0014.pgc - 대사 통계 배치 (RC_BT_0014)
 *
 * 지정 영업일의 원장 전건을 커서로 순회하며 금액 통계를 산출한다.
 * (리포트 전용 - 상태변경/트랜잭션 없음, 접속/해제만 수행)
 * 업무규칙: 건수/최소금액/최대금액/합계금액을 누적하고, 매입확정('M') 및
 *          정산완료('S') 건을 매입건으로 계수한다.
 *          평균 = 합계/건수, 매입율 = 매입건*100/건수 (0 나눗셈 방어).
 *
 * 실행:  rc_bt_0014 <YYYYMMDD> [db@host]
