 * [업무 개요]
 *   운영자가 특정 전표의 상태코드를 수동으로 정정할 때 사용한다. 잘못 전이된
 *   상태를 바로잡는 관리 기능이므로, 허용된 상태코드(R/M/U/S) 만 지정할 수
 *   있도록 엄격히 검증하고, 정정 전 상태를 감사(監査) 목적으로 함께 반환한다.
 *
 * [허용 상태코드]
 *   R(접수) / M(처리완료) / U(불일치) / S(정산완료)
 *   그 외 문자열은 RESP_INVALID 로 거부한다. (lg_ol_0025_valid_status)
 *
 * [처리 절차]
 *   1) KEY, NEWSTATUS 추출.
 *   2) NEWSTATUS 유효성 검증(1자리 + 허용집합).
 *   3) tx_begin 후 현재 상태(OLDSTATUS) 확보(없으면 RESP_NOMERCH).
 *   4) status 를 NEWSTATUS 로 UPDATE, tx_commit.
 *
 * [응답 필드]
 *   RESPCODE   처리결과코드   KEY 처리키(에코)
 *   OLDSTATUS  정정 전 상태   NEWSTATUS 정정 후 상태
