fix: company metadata placeholder 제거 — sector/industry 실제 값 보장

- financial.py: 캐시 히트 시 company 블록을 CMS에서 항상 refresh
  (financial:data:* 캐시에 stale company 블록이 임베드된 문제 해결)
- financial_service.py: _is_placeholder() 확장 — exchange=null인
  Technology/Software 종목도 placeholder로 감지 (AVGO-류 미검출 해결)
- company_metadata_service.py: _sync_fetch() 개선 — yfinance 첫 번째
  호출은 auth 토큰 없이 partial 응답을 반환할 수 있으므로 sector가
  없는 EQUITY 종목에 대해 한 번 retry (auth 캐시 후 full data 획득)
- docker-compose.yml: 컨테이너 시작 시 yfinance_plus 로컬 버전을
  site-packages에 자동 복사 (docker restart 후 override 소실 방지)

검증: USAS/CPRX/HE/ACHR/AVGO 모두 실제 sector/industry/exchange 반환
