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.

+CCTV sources with `"feedType": "hls"` and a registered HTTP(S) `.m3u8`
+URL play through a lazily loaded hls.js decoder shared by the monitor plane
+and panel. DelDOT uses its official HTTPS HLS catalog links. Disable that
+pack with `CCTV_DELDOT_ENABLED=0`.
+
+The server allows two concurrent sessions. Each retains at most 12 segments
+and 24 MiB in memory; individual downloads are capped at 4 MiB with a ten
+second deadline. There are no segment files or ffmpeg processes. Redirects,
+off-origin references, encrypted playlists and non-MPEG-TS segments are refused.
+Each decoder has its own client lease (at most eight per session), including
+native HLS. Closing it releases only that lease; abandoned leases expire after
+15 seconds without access. The last release stops upstream work. Failed live video
+uses the existing still/Street View/synthetic fallback, which is not live video.
+RTMP-only sources are not supported by this integration.
