feat: 浏览器类型字段改为下拉选择

- catalog.json: WebBrowser_Create/V2/V3/CreateBackground 的 type 字段补 options（内置运行浏览器/Chrome/Edge，label 与存储值分离）
- shared/types.ts: CatalogField.options 支持字符串或 {label,value} 对象
- Properties.tsx: select/radio 选项归一化渲染 label；当前值不在选项中时追加显示（兼容历史手填值如 zexplorer）
- typecheck 通过；全量 vitest 除 4 项依赖真实 COM 的历史失败外全部通过
