Weather backend: NWS active alerts + nearest-METAR wind, cached (Refs #237)

Browse Source 
GET /weather/alerts — api.weather.gov/alerts/active for settings.nws_area,
sent with the NWS-required User-Agent, cached weather_alerts_ttl_s (90 s)
with single-flight refresh. Zone-based alerts (geometry null) get their
polygons from affectedZones (24 h zone cache, api.weather.gov/zones/ only);
any still unresolved are returned in zone_only, never dropped. Failed
refresh keeps last-good data + error + fetched_at; a payload where no
feature parses is a schema-change error. Optional bbox filter.

GET /weather/wind — nearest METAR (aviationweather.gov /api/data/metar,
bbox query) within 75 km, cached 5 min per 0.5-degree cell; VRB wind and
stale reports flagged; available:false with a reason otherwise.

Both behind require_service_or_firebase_token like /traffic.
