Auth session 持久化 + 多分辨率跑道图表 + 拖拽缩放

- middleware: refreshMiddlewareSession 前置刷新 Supabase token
- backend-auth: getUser() 优先触发 refresh，再 getSession 拿新 token
- Dashboard: onAuthStateChange 实时更新 proAccess + 15min getSession 心跳
- detail proxy: 新增 city/[name]/detail 代理，透传 resolution 参数
- city_payloads: aggregate_runway_history + build_runway_band_history 跑道聚合
- chart: 10m→1m 自适应分辨率 + zoom 拖拽 + 跑道温区 Area + Runway Details 开关
