修复高频机场数据源：AMOS接入airport_primary、Taipei CWA补充mgm_nearby、Paris AROME缓存

- Seoul/Busan: AMOS 跑道传感器纳入 airport_primary 链路（MADIS之后、MGM之前）
    - Seoul/Busan: 跑道温度生效时同步更新 current_obs_time，去重不再依赖慢速METAR
    - Taipei: 新增 _attach_cwa_settlement_nearby，将CWA数据注入 mgm_nearby（icao=RCSS）
    - Paris: AROME HD 抓取新增 10分钟内存缓存（模型15分钟更新），obs_time 为空时补 UTC 时间
    - Istanbul/Ankara MGM 链接修复为直接跳转机场站点页面

    Scope-risk: LOW — 170 测试通过，ruff 零告警
    Tested: python -m pytest -q (170 passed), ruff check .
