테이블 타입 관리 페이지에서 PK/IDX 토글 후 UI 상태가 갱신되지 않던 버그.

1. Backend: TableManagementService.parseColumnArray
   - PostgreSQL ARRAY_AGG 가 java.sql.Array (PgArray) 로 오는데
     List/String 만 처리해서 항상 List.of() 반환 → columns 빈 배열
   - 조치: java.sql.Array 분기 추가, arr.getArray() → Object[] → List<String>

2. Frontend: loadConstraints
   - 백엔드는 result.put("primary_key", ...) 로 snake_case 반환
   - 프론트가 data.primaryKey 로 camelCase 로 읽어 undefined → 항상 빈 PK
   - 조치: data.primary_key 로 통일

이전 PR (#14) 의 IDX payload 수정과 합쳐, PK/IDX 토글이 API 호출/DB 적용/
UI 반영까지 한 사이클로 동작.

검증:
- gradle compileJava BUILD SUCCESSFUL
- solution.invyone.com 에서 IDX 토글 양방향 확인 예정
