문제:
- Oracle DB에 INSERT 해도 데이터가 실제로 저장되지 않음
- executeQuery에서 autoCommit 옵션이 없었음

수정:
1. 쿼리 타입 확인 (INSERT/UPDATE/DELETE/MERGE)
2. DML 쿼리는 autoCommit: true 설정 ✅
3. SELECT 쿼리는 autoCommit: false (기본값)

로깅 추가:
- isDML 확인
- autoCommit 상태
- rowsAffected 추가

결과:
- ✅ INSERT 실행 후 자동 COMMIT
- ✅ UPDATE/DELETE도 자동 COMMIT
- ✅ SELECT는 영향 없음
- ✅ 오라클 데이터 정상 저장
