I Luk Kim f19d31f125 feat: /form4 auto-fetch fallback + targeted backfill 지원
- /form4/{ticker}, /form4/aggregate/{ticker}: DB에 ticker 데이터 없으면 SEC에서 800일치 자동 fetch (index_form4s)
- force_refresh 파라미터 추가로 on-demand 재인덱싱 지원
- Form4Response, Form4AggregateResponse에 metadata 필드 추가 (auto_fetched, fetched_count)
- bootstrap_form4_by_ticker.py: --tickers 옵션 추가로 특정 ticker만 targeted backfill 가능
- audit_form4_coverage.py: universe 커버리지 검증 스크립트 신규
