생산관리 M-BOM 변경이력 다이얼로그(PR-B4) + 그리드 컬럼 폭 다듬기

운영 productionplanning.getMbomHistory (3448~3470) 1:1 이식:
  · backend mbomService.getHistory(projectObjid) — project 단위 mbom_header 변경이력
    시간순 최신 우선, USER_INFO join 으로 변경자명 함께
  · GET /api/production/mbom/history/:projectObjid
  · frontend MbomHistoryDialog — 5컬럼 그리드(변경일시/유형/내용/변경자/M-BOM품번)
    CREATE=파란 뱃지, UPDATE=황색 뱃지, max-w-900px
  · MbomDetailDialog toolbar 에 "변경이력" 버튼 (편집 모드 아닐 때만 노출)

PR-B1 의 history 저장 결과를 사용자가 직접 확인할 수 있도록 보는 화면 마무리.

부수: production/mbom/page 그리드 컬럼 폭 정돈 + summaryStats(전체/페이지/수주합/M-BOM 비율).
