feat: DB WAL 모드 적용, .env.example 정리 (#210, #213, #216)
Some checks failed
CI / test (pull_request) Has been cancelled

- #210: init_db()에 WAL 저널 모드 적용 (파일 DB에만, :memory: 제외)
  - 대시보드(READ)와 거래루프(WRITE) 동시 접근 시 SQLite 락 오류 방지
  - busy_timeout=5000ms 설정
- #213: RATE_LIMIT_RPS 기본값 2.0으로 통일 (.env.example이 5.0으로 잘못 표기됨)
- #216: .env.example 중요 변수 추가 및 정리
  - KIS_BASE_URL 모의/실전 URL 주석 명시 (포트 29443 수정 포함)
  - MODE, TRADE_MODE, ENABLED_MARKETS, PAPER_OVERSEAS_CASH 추가
  - GEMINI_MODEL 업데이트 (gemini-pro → gemini-2.0-flash-exp)
  - DASHBOARD 설정 섹션 추가

테스트 2개 추가 (WAL 파일 DB 적용, 메모리 DB 미적용 검증)
