feat: Phase 3.16 데이터 관리 서비스 Raw Query 전환 완료

4개 서비스 18개 Prisma 호출 전환 완료:

1. **EnhancedDynamicFormService** (6개)
   - validateTableExists - information_schema 조회
   - getTableColumns - 테이블 컬럼 정보 조회 with 캐싱
   - getColumnWebTypes - 웹타입 정보 조회
   - getPrimaryKeys - Primary Key 조회
   - performInsert - 동적 INSERT with RETURNING
   - performUpdate - 동적 UPDATE with RETURNING

2. **DataMappingService** (5개)
   - getSourceData - 소스 테이블 데이터 조회
   - executeInsert - 동적 INSERT
   - executeUpsert - ON CONFLICT DO UPDATE
   - executeUpdate - 동적 UPDATE
   - disconnect - 제거 (Raw Query 불필요)

3. **DataService** (4개)
   - getTableData - 동적 SELECT with 동적 WHERE/ORDER BY
   - checkTableExists - information_schema 테이블 존재 확인
   - getTableColumnsSimple - 컬럼 정보 조회
   - getColumnLabel - 컬럼 라벨 조회

4. **AdminService** (3개)
   - getAdminMenuList - WITH RECURSIVE 쿼리
   - getUserMenuList - WITH RECURSIVE 쿼리
   - getMenuInfo - LEFT JOIN으로 회사 정보 포함

기술적 성과:
- 변수명 충돌 해결 (query vs sql)
- WITH RECURSIVE 쿼리 전환
- Prisma include → LEFT JOIN 전환
- 동적 쿼리 생성 (WHERE, ORDER BY)
- SQL 인젝션 방지 (컬럼명 검증)

진행률: Phase 3 173/186 (93.0%)
