 * ac_ol_0027.pgc - 매입 온라인 서비스 (AC_OL_0027)  [tier=easy]
 *
 * 매입 통계: 지정 영업일의 완료(status='M') + 정산완료(status='S') 건을
 * 집계하여 건수/매입금액합계/수수료합계/건당 평균금액을 산출한다.
 * 일별 매입 현황 대시보드/모니터링 화면에서 조회하는 통계 전용
 * 서비스이다.
 *
 * 평균금액은 매입금액합계를 건수로 나눈 값이며, 대상 건이 0건이면
 * 0으로 가드하여 0-division 을 방지한다. 실효 수수료율(bp)도 함께
 * 산출하여 가맹점 수수료율 이상 징후를 조기에 확인할 수 있게 한다.
