/* ---------------------------------------------------------------------------
 * IK000111_P01.xfdl 변환본 — IK 판매장려금 엑셀 업로드 모달 (695x469).
 * Modal #A 24번째 인스턴스 + *업로드 카테고리 2번째* (IK_Main_P06 의 batch delete 후).
 *
 * 신규 디자인: *5 탭 (T01-T05) 공통 모달* — tabKey 별 컬럼 / endpoint 분기.
 *   - REBATE_CODE / EXCP_REBATE / SPCL_REBATE / NTWK_CODE / PAY_YN
 *   - 동일 DOM + tabKey 별 그리드/헤더/저장 endpoint 분기
 *   → *변환 분할의 공유 의존성 = 5 stub 한 번에 해결*
 *
 * 구조:
 *   - 헤더: 업로드 정형색 (#2c4368)
 *   - 파일 선택 + "파일찾기" + "폼 다운로드" (탭별 컬럼)
 *   - 미리보기 그리드 (탭별 다른 컬럼)
 *   - 저장 / 닫기
