feat(infra): naver-fetch 워커 2D 표시 — fetcher 라벨·수집 상태·Naver Fetch 타이틀

BE가 /api/agent-office/nodes에 등재한 naver-fetch(kind=fetcher) 워커 카드가
데이터 구동 2D 패널에 자동 표시되도록 statusVisual 매핑 보강.
- kindLabel('fetcher') → '수집 워커'
- workerStateLabel state:'fetching' → '수집 중'
- WORKER_TITLES 'naver-fetch' → 'Naver Fetch'
TDD: statusVisual.test.js 3케이스 추가(RED→GREEN).
