fix: MySQL 8.0 호환성 문제 해결 - db.execute → db.query 변경

🔧 주요 변경사항:
- WorkAnalysis.js: getRecentWork() 함수에서 db.execute → db.query로 변경
- Redis 연결 설정: socket 방식으로 업데이트 (Redis v5+ 호환)
- Docker Compose: Redis 서비스 추가 및 네트워크 단순화

🎯 해결된 문제:
- 'Incorrect arguments to mysqld_stmt_execute' 오류 해결
- 시놀로지 MySQL 8.0 환경에서 파라미터 바인딩 호환성 문제 해결
- Redis 연결 실패 문제 해결

📋 참고사항:
- MySQL 8.0의 ONLY_FULL_GROUP_BY 모드와 Node.js 드라이버 호환성 문제
- db.execute vs db.query 차이점은 MYSQL_COMPATIBILITY_NOTES.md 참조
