refactor: 中间栏三层架构 — useUI 组件体系 + useModelUI Hook

- 新建 useUI/ 目录：12 个文件，10 个 Qt 控件 → antd 组件封装 + 类型 + 注册表
- 新建 useModelUI Hook：param_schema → UIFieldConfig[] 自动映射
- ModelInputForm 瘦身 ~160 行：删除 buildParamDescriptors/renderParamControl/文件状态管理
- WIDGET_MAP: Record<string, ComponentType<WidgetProps>> — 零 any，完全类型安全
- 新增控件只需两步：创建组件文件 + 在 WIDGET_MAP 加一行
- 删除旧 widgets/ 目录
