修正市场监控温度数据源：接入 NOAA MADIS 5分钟高频数据并优化展示

- 首尔/釜山：隐藏大号跑道温度值，改为"跑道温度"标签（跑道表面温度 ≠ 空气温度）
- US 城市：MADIS HFMETAR 5分钟小数温度接入 airport_primary，前端优先读取
- 其他城市：整数值不再强制 toFixed(1) 追加虚假 .0 精度
- 后端：weather_sources.py 注入 madis_hfmetar_current 到 results
- 后端：country_networks.py 的 _airport_primary_from_raw 新增 MADIS 优先分支
- 文档：更新 AIRPORT_REALTIME_SOURCES.md 新增 11 个 US 城市
- 文档：更新 CLAUDE.md 补充市场监控、高频数据管道、Country Network Provider 架构
