feat: config.yaml 기반 설정 마이그레이션 및 대시보드/종목조회 기능 추가

- config.yaml에서 직접 KIS 설정 관리 (BaseSettings 제거)
- 대시보드 KIS 계좌 잔고 실시간 연동, 로컬 DB 폴백
- 종목 조회 페이지: 시세/호가/일봉차트 (canvas) 구현
- 호가 REST API 엔드포인트 (/api/stocks/{code}/orderbook) 추가
- 토큰 캐시(.auth_cache.json) 저장/복원, 1분 재시도 제한
- KIS WebSocket 자동 연결 + 재연결 로직
- httpx 타임아웃 10초→30초, 라우터 타임아웃 핸들링 (504)
- rate limit: requests_per_second 2.0 (모의투자 초당 2건)
- 사이드바 3메뉴: 실거래 / 과거기록 / 종목조회
