feat: V2/Unified 컴포넌트 설정 스키마 정비 및 레거시 컴포넌트 제거

- 레거시 컴포넌트를 제거하고, V2 및 Unified 컴포넌트 전용 Zod 스키마와 기본값 레지스트리를 통합 관리합니다.
- V2 컴포넌트와 Unified 컴포넌트의 overrides 스키마를 정의하고, 기본값과의 병합 로직을 추가하였습니다.
- 레이아웃 조회 시 V2 테이블을 우선적으로 조회하고, 없을 경우 V1 테이블을 조회하도록 개선하였습니다.
- 관련된 테스트 계획 및 에러 처리 계획을 수립하여 안정성을 높였습니다.

+# 프로젝트: V2/Unified 컴포넌트 설정 스키마 정비
+
+## 개요
+레거시 컴포넌트를 제거하고, V2/Unified 컴포넌트 전용 Zod 스키마와 기본값 레지스트리를 한 곳에서 관리한다.
+
+## 핵심 기능
+1. [x] 레거시 컴포넌트 스키마 제거
+2. [x] V2 컴포넌트 overrides 스키마 정의 (16개)
+3. [x] Unified 컴포넌트 overrides 스키마 정의 (9개)
+4. [x] componentConfig.ts 한 파일에서 통합 관리
+
+## 정의된 V2 컴포넌트 (18개)
+- v2-table-list, v2-button-primary, v2-text-display
+- v2-split-panel-layout, v2-section-card, v2-section-paper
+- v2-divider-line, v2-repeat-container, v2-rack-structure
+- v2-numbering-rule, v2-category-manager, v2-pivot-grid
+- v2-location-swap-selector, v2-aggregation-widget
+- v2-card-display, v2-table-search-widget, v2-tabs-widget
+- v2-unified-repeater
+
+## 정의된 Unified 컴포넌트 (9개)
+- unified-input, unified-select, unified-date
+- unified-list, unified-layout, unified-group
+- unified-media, unified-biz, unified-hierarchy
+
+## 테스트 계획
+### 1단계: 기본 기능
+- [x] V2 레이아웃 저장 시 컴포넌트별 overrides 스키마 검증 통과
+- [x] Unified 컴포넌트 기본값과 스키마가 매칭됨
+
+### 2단계: 에러 케이스
+- [x] 잘못된 overrides 입력 시 Zod 검증 실패 처리 (safeParse + console.warn + graceful fallback)
+- [x] 누락된 기본값 컴포넌트 저장 시 안전한 기본값 적용 (레지스트리 조회 → 빈 객체)
+
+## 에러 처리 계획
+- 스키마 파싱 실패 시 로그/에러 메시지 표준화
+- 기본값 누락 시 안전한 fallback 적용
+
+## 진행 상태
+- [x] 레거시 컴포넌트 제거 완료
+- [x] V2/Unified 스키마 정의 완료
+- [x] 한 파일 통합 관리 완료
