fix(orders/admin): 발주 리스트 컬럼 겹침/툴팁 떠다님 제거

- <tr title=...> 의 lock 메시지 hover 툴팁이 다음 행 위로 떠다니던 문제 해결 — title 제거.
- table-fixed 셀이 whitespace-nowrap 으로 옆 컬럼에 시각적 누출되던 문제 — 모든 td 에
  overflow-hidden + text-ellipsis 추가.
- 컬럼 폭 확장: 발주번호 100→112, 발주일 82→100, 합계 100→110, 상태 72→78.
- 좌측 패널 최소폭 560→640 으로 키워 업체 컬럼이 화면에 꽉 차게 한다.
