I Luk Kim ffaed4fc9d fix: 서버 응답불능 — limit-concurrency 20 + asyncio yield points 
BaseHTTPMiddleware는 요청당 2개 asyncio task를 생성한다.
--limit-concurrency 100은 여전히 200개 task가 event loop를 포화시켜
health check 포함 모든 요청이 block됐다.

변경 사항:
- docker-compose.yml: --limit-concurrency 100 → 20
  (세마포어 10개 처리 + 10개 대기, 나머지 20초과 시 503으로 즉시 반환)
- alpaca_price_service.py: upsert 루프 청크 사이 + Phase 4 ORM 일괄 생성 후
  await asyncio.sleep(0) 추가 — 동기 CPU 블로킹 중 event loop yield 보장
