Tel Aviv 机场观测切换至 IMS Lod Airport 实时数据源

Browse Source 
新增 IMS (Israel Meteorological Service) 数据抓取模块，以 Lod Airport
(station 225) 官方观测替代 NOAA METAR LLBG 作为 airport_primary。
IMS 数据接入 _airport_primary_from_raw 优先级链，高于 plain METAR
但保留 METAR 集群回退路径。

Constraint: IMS API (ims.gov.il/en/hourly_observations) 仅每小时更新
Confidence: high
Scope-risk: 仅影响 Tel Aviv 城市，其余 51 城数据流不变
Tested: 端到端验证 IMS 取数 → airport_primary → provider 路由链
