feat: Phase 2.1 Stage 1 complete - Basic CRUD converted (6/46)

Stage 1 완료: 기본 CRUD Raw Query 전환

✅ 전환 완료 (6개):
1. createScreen() - 화면 생성 (중복확인 + INSERT)
2. getScreensByCompany() - 목록 조회 (페이징 + 동적 WHERE)
3. getScreenById() - ID로 조회
4. updateScreen() - 화면 수정 (권한확인 + UPDATE)
5. deleteScreen() - 소프트 삭제 (트랜잭션)
6. getScreenByCode() - 코드로 조회

📊 진행률: 6/46 (13%)
🎯 다음: Stage 1 나머지 조회 함수 (getScreens, getAllScreens)
