fix(batch): 빈 화면 원인이던 openTab 키명 정정 + 본문 풀폭 적용

문제 1: 배치 수정/생성 탭이 빈 화면
- Tab type 정의는 admin_url (snake_case) 인데 호출자가 adminUrl (camelCase)
  로 전달 → TabPageRenderer 매칭 실패 → null 렌더 → 빈 화면
- 콘솔 경고: "[TabPageRenderer] 렌더링 불가 — 매칭 조건 없음" (TabContent.tsx:268)
- 11곳 (4파일) 의 adminUrl → admin_url 정정

문제 2: 리스트/편집 본문이 좁은 가운데 컬럼에 박혀있음
- batchmngList/page.tsx: max-w-[720px] → w-full
- batchmngList/edit/[id]/page.tsx: max-w-[640px] → w-full

해당 파일:
- batchmngList/page.tsx
- batchmngList/edit/[id]/page.tsx
- batchmngList/create/page.tsx
- batch-management-new/page.tsx
