I Luk Kim 7f28266bd6 feat: company metadata 안정화 — 실제 sector/industry/exchange 보강 
- CompanyMetadataService 신규: Redis → registry → yfinance 순서 조회,
  semaphore(5) 보호, 24h cache, companies + registry UPSERT
- GET /company/{ticker} + POST /company/bulk (최대 100개, 세션 격리)
- companies 테이블에 exchange/country/market_cap 컬럼 추가 (alembic)
- CompanyInfo 스키마 exchange/country/market_cap 필드 추가
- _is_placeholder() 체크: 기존 "Technology/Software/XYZ Corporation" 행 재보강
- financial endpoint: financials/price 실패 시 company block은 유지 (500 방지)
- bulk endpoint: 각 ticker마다 독립 AsyncSession으로 동시 세션 충돌 방지
- scripts/backfill_registry_sector.py: 9376개 NULL-sector 일괄 보강 스크립트

검증: AU→Basic Materials, USAS→Basic Materials, CPRX→Healthcare,
      HE→Utilities, ACHR→Industrials, ZZZZZZ→404, AAPL 기존 데이터 유지
