MobileCityPicker 原依赖扫描终端 API rows，该 API 仅 Pro 用户触发，
导致访客/免费用户 cityListRows 为空，所有城市被 pickCityRow 过滤掉。
现新增 cityListRows fallback：无 scan 数据时从 store.cities +
citySummariesByName 构建行数据，保证所有用户可见并搜索城市列表。

Constraint: fallback rows 缺少 metar/target 字段，但 MobileCityPicker 仅消费 display/temp/deb/airport 字段，不影响渲染。
