feat(vehicle): 优化车辆管理相关表单布局和字段

- 车牌号组件改为单一输入框，去除省简称和颜色选择，实现完整车牌号输入
- 重写车牌号校验逻辑，校验完整车牌号格式，错误提示更加明确
- 车辆新增/编辑弹窗输入框宽度统一调整，基础信息和资质图片区按四列布局排列
- 修复所有组织字段宽度不一致问题，补充级联选择器样式支持
- 司机新增/编辑弹窗调整为四列布局，调整字段排列顺序，提升界面整洁度
- 客商档案中「客商类型」改名为「客商分类」，新增「客商类型」字段支持外部客商和内部组织区分
- 上传证件项 label 贴顶问题修复，统一提升到全局样式实现垂直居中
- 移除车牌颜色只读展示，审核弹窗同步删除车牌颜色字段
- 保持后端接口兼容，数据库字段未变，OCR同步调用链路无影响
