refactor: API 모델 완전 통합 (vo + internal/model -> model)

중복 제거 및 단일 모델 구조로 통합

## 변경사항

### 통합된 구조
```
api/model/
├── Envelope.java                    # 공통 Envelope
├── VehicleApiResponseVO.java        # 최상위 응답
├── request/                         # 요청 모델
│   ├── BasicRequest.java           # 기본정보 요청
│   └── LedgerRequest.java          # 등록원부 요청
└── response/                        # 응답 모델
    ├── BasicResponse.java          # 기본정보 응답
    ├── LedgerResponse.java         # 등록원부 응답
    ├── VehicleBasicInfoVO.java     # 기본정보 VO
    ├── VehicleLedgerVO.java        # 등록원부 VO
    ├── VmisCarBassMatterInqireVO.java
    ├── VmisCarLedgerFrmbkVO.java
    └── VmisCarLedgerFrmbkDtlVO.java
```

### 제거된 중복 패키지
- ❌ api/vo/ (삭제)
- ❌ api/internal/model/ (삭제)

### 효과
- Internal/External 모두 **동일한 모델** 사용
- 중복 없는 **단일 진실 공급원**
- 패키지 구조 단순화 및 명확화

## 빌드 결과
✅ BUILD SUCCESSFUL
