style: 표/패널 UI 전면 통일 + 화면설명 드로어·글씨크기·탭 개선

표 디자인
- 모든 표를 가벼운 스타일로 통일(.data-table 경량화: 작은 회색 헤더·연한 구분선·hover)
- 표/패널 바깥 테두리 둥글게(rounded-lg) 일괄 적용, 표 래퍼에 패딩 카드(p-4) 통일
- 표 헤더·데이터 정렬을 전 화면 좌측 기준으로 통일
  - .data-table th/td text-align:left (전역), 흩어진 center/right 정렬 정리
  - 재디자인 Tailwind 표(포장단위·단가·기본코드·담당자·업체·판매대행소·무료대상자·지정판매소)도 셀 좌측화
- 기본정보관리 등 나머지 소메뉴 표를 기본 코드 관리 스타일(가벼운 표·상태 pill)로 재디자인

워크스페이스/공통
- "이 화면 설명" → 새 탭 대신 우측 드로어 팝업(현재 화면과 동시에 보기, Esc·드래그 폭조절)
- 상단바 글씨 크기 조절(A−/A+), 작업 내용에 zoom 적용
- 탭 최대치 도달 시 자동 삭제 대신 안내 토스트, "모두 닫기"(업무 현황 탭은 보존)
