 * cl_ol_0007.pgc - 마감 온라인 서비스 (CL_OL_0007)  [tier=medium]
 *
 * 마감 잔액검증. 요청 영업일(BIZDATE)의 정산완료(S) 건에 대해 거래금액
 * 합계(Σamount), 수수료 합계(Σfee), 순액(Σamount-Σfee)을 singleton
 * SELECT 로 산출하고, 요청 기대순액(EXPECTNET)과 비교하여 잔액 일치여부를
 * 판정한다. 불일치 시 RESP_INVALID. (read-only 검증)
 *
 * ── 서비스 계약(Contract) ────────────────────────────────────────────
 *  입력 필드:
 *    BIZDATE    (필수) 영업일(YYYYMMDD)
 *    EXPECTNET  (선택) 기대 순액(원, 미제출 시 0 으로 비교)
 *  출력 필드:
 *    RESPCODE   0000=잔액일치 / 9001=불일치·입력오류 / 9999=시스템오류
 *    BIZDATE    검증 대상 영업일
 *    SETTLECNT  정산완료(S) 건수
 *    AMTSUM     거래금액 합계(Σamount)
 *    FEESUM     수수료 합계(Σfee)
 *    NETAMT     순액(= AMTSUM - FEESUM) / NETWON 한글 표기
 *    EXPECTNET  기대 순액
 *    DIFFNET    순액 차이(실제-기대)
 *    BALANCED   잔액 일치여부(Y/N)
 *
 * ── 잔액검증 규칙 ────────────────────────────────────────────────────
 *    · 마감완료(S) 건의 거래금액과 수수료를 각각 합산한다.
 *    · 순액 = Σamount - Σfee 로, 가맹점 실지급 예정액을 의미한다.
 *    · 순액이 기대순액과 정확히 일치할 때만 잔액일치(RESP_OK)로 본다.
