fix(배치관리): 대시보드 NaN 제거 + 24시간 차트 더미데이터 → 실데이터

- 백엔드: getBatchManagementGlobalSparklineData 쿼리 추가 (generate_series 로
  24개 슬롯 고정, 회사 전체 배치 LEFT JOIN 집계)
- 백엔드: GET /api/batch-management/sparkline 엔드포인트 추가
- 프론트: BatchStats/SparklineData 타입을 백엔드 mapper 의 snake_case 응답키와
  일치시킴 (today_count, today_failed_count, hour_slot, success_count, ...).
  키 미스매치로 stats 카드가 NaN 으로 표시되던 버그 해소
- 프론트: GlobalSparkline 컴포넌트의 Math.random() 더미 막대를 실데이터 prop 으로
  교체. row-level Sparkline 도 동일 키 정렬로 정상 렌더되도록 수정
