feat: 데이터 도메인 사전 + 데이터 사전 시스템 (V20)

3 agents 병렬 작업 (dba / api / frontend) 결과물 + SQL 버그 2건 fix.

DB (V20__데이터사전.sql):
- data_domain (domain_code PK, category, data_type, length/precision/scale,
  format_pattern, validation_regex, masking_type, encrypted, ...)
- data_dictionary (dict_id PK, table_name, column_name, domain_code FK,
  column_label, is_pk/is_fk/fk_reference, business_rule, sample_value, ...)
- VIEW v_data_dictionary_full: information_schema + pg_description +
  data_dictionary + data_domain 4-way LEFT JOIN
  → ga 스키마 모든 컬럼 자동 노출 (사전 미등록 컬럼도 회색 표시)
- 도메인 30개 초기 데이터 (IDENTIFIER 7 / PII 6 / MONEY 5 / RATE 3 /
  DATE 4 / CODE 4 / TEXT 3 / JSON 2)
- 사전 매핑 50개 (agent 10 / contract 7 / recruit_ledger 9 /
  settle_master 9 / payment 6)
- 메뉴 SYSTEM_DATA_DOMAIN, SYSTEM_DATA_DICT 등록 + 권한

Backend:
- ga-core VO 9개 + Mapper 2개 + XML 2개
- ga-api Service 2 (도메인 삭제 시 사전 참조 검증) + Controller 2
- 엔드포인트:
  · /api/data-domains (CRUD + /options)
  · /api/data-dictionary (CRUD + /tables + /full?tableName=)

Frontend:
- api/dict.ts (13 endpoints)
- pages/system/DataDomainList.tsx — 카테고리 색상 Tag, 마스킹/암호화 표시,
  ModalForm 등록/수정/삭제
- pages/system/DataDictionary.tsx — 좌(테이블 목록 + prefix 그룹핑) +
  우(v_data_dictionary_full 조회, 사전 미등록 컬럼은 회색+점선 추가 버튼)
- App.tsx + MenuIcon.tsx 매핑 추가

Bug fix:
- DataDomainMapper: WHERE is_active = true → 'Y' (CHAR vs boolean)
- DataDictionaryMapper.selectFromView: ORDER BY sort_order 제거
  (view 에 없는 컬럼)

검증:
- ./gradlew :ga-api:bootJar 통과
- Flyway V20 운영 DB 적용 (17초)
- 4 엔드포인트 모두 200 응답
- agent 테이블 15컬럼 사전 자동 노출 + 도메인 매핑 정상
