feat(weather): add globe wind, observed weather and cyclone context (#617)

Wind (NOAA GFS and ECMWF IFS: animated particles, colour field, a reading at map centre), observed weather (NOAA MRMS radar, GOES and NESDIS infrared clouds, lightning density) on one shared history timeline, NHC and CPHC cyclone advisories with tracks and cones, and a WEATHER panel in the right rail. On 3D Tiles the observed products render as raised shells with a sharper window around the view.

+1. Turn on **CCTV**, fly to Dover, DE, and activate **DE 1 @ Main Toll Plaza**. ✅ Within ~30 s the monitor plane and the panel preview both show moving video,.
+2. Leave it for **five minutes**. ✅ Continuous playback; at most a short hitch about once a minute (the agency restarts its stream on a timer). ❌ A freeze that does not recover, or the panel picture stopping while the plane keeps moving.
+3. Toggle **PROJECTION** off. ✅ The panel keeps playing; the plane and the active camera's cone hide.
+4. Switch to **DE 8 @ Saulsbury Rd**, then back. ✅ Each switch resumes within ~10 s with no stale frame from the previous camera.
