 * cl_ol_0004.pgc - 마감 온라인 서비스 (CL_OL_0004)  [tier=easy]
 *
 * 마감후 집계 조회. 요청 영업일(BIZDATE)의 정산완료(S) 건에 대해
 * 건수 / 거래금액 합계 / 수수료 합계 / 순액(합계-수수료)을 singleton
 * SELECT 로 산출하여 응답한다. read-only 조회 서비스이다.
 *
 * ── 서비스 계약(Contract) ────────────────────────────────────────────
 *  입력 필드:
 *    BIZDATE    (필수) 영업일(YYYYMMDD)
 *  출력 필드:
 *    RESPCODE   0000=정상 / 9001=입력오류 / 9999=시스템오류
 *    BIZDATE    집계 대상 영업일
 *    SETTLECNT  정산완료(S) 건수
 *    AMTSUM     거래금액 합계(Σamount, 원)
 *    FEESUM     수수료 합계(Σfee, 원)
 *    NETAMT     순액(= AMTSUM - FEESUM, 원)
 *    NETWON     순액 한글 표기
 *
 * ── 집계 규칙 ────────────────────────────────────────────────────────
 *    · 마감완료(status='S') 건만 집계 대상으로 삼는다.
 *    · 순액(NETAMT)은 가맹점 지급 기준액으로, 거래금액에서 매입
 *      수수료(fee)를 차감하여 산출한다.
 *    · 집계 대상이 0건이면 모든 합계를 0 으로 응답하고 경고 로그를 남긴다.
 *
 * ── 처리 흐름 ────────────────────────────────────────────────────────
 *    1) BIZDATE 추출/형식검증
 *    2) status='S' 대상 count/Σamount/Σfee singleton SELECT
 *    3) 순액 산출 및 응답 TXBUF 구성
