feat: SEC Form 4 PIT + SC 13D/G activist ownership API
## 신규 엔드포인트
- GET /insider/form4/{ticker} — PIT-safe Form 4 거래 목록 (as_of 필수)
- GET /insider/form4/by-date/{date} — 특정 공시일 cross-ticker 거래
- GET /insider/form4/aggregate/{ticker} — 내부자 매수 집계 (window_days)
- GET /ownership/13dg/{ticker} — SC 13D/G activist 이벤트 (as_of 필수)
- GET /ownership/13dg/active — 현재 활성 activist 포지션 (window function PIT)
## 데이터 인프라
- activist_ownership_events 테이블 (42,329행, 최근 2년 bootstrap 완료)
- insider_transactions: is_ceo/is_cfo/is_c_suite/purchase_pct_of_holding/owner_relationship 컬럼 추가
- SECFullIndexService: company.idx fixed-width 파서, form345.zip 파서
- ActivistOwnershipService: SGML header issuer 해석 + cover-page XML/HTML enrich
- SEC ingest scheduler: 매 영업일 09:00 ET daily ingest + 30분 enrich job
- scripts: bootstrap_form4_by_ticker.py, bootstrap_form4_2y.py, bootstrap_13dg.py
## 버그 수정 (enrich 품질)
- filing_url double edgar/ prefix 제거
- XML: classPercent + amountBeneficiallyOwned + reportingPerson... 태그 추가
- HTML: 태그 제거 후 regex 적용 (CSS 10pt → shares 오인식 방지)
- HTML: ownership_pct > 100 방어 로직

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
