Show more info in the per-road popup

Show the speed, one-wayness, whether it's been edited, any bus routes along it, and maybe some indication it's a special pedestrianized street (which should have filters on/near it enforcing that, but still worth calling out, in the same way that OSM carto does: https://www.openstreetmap.org/#map=18/53.479708/-2.247970).

查找在前端渲染每条道路弹窗的代码，可能位于 Yew 或 Leptos 之类的 Rust Web 框架中。确定道路数据（速度、单行道、编辑状态、公交线路、步行化状态）在哪里获取和显示。扩展弹窗模板以包含这些字段，并参考 OSM carto styling 来处理步行街。通过在本地运行 Web 应用并检查一条道路来测试。
