feat: add Statens vegvesen (Norway) road cameras as a CCTV pack

Norway's ~850 working road cameras load from one keyless GeoJSON request
to the agency's OGC API view of its DATEX 3.1 CCTV table, so no DATEX
account is needed. Faulty cameras are dropped, every camera sits under a
"Norway" category, and the ~135 that publish HLS play as live video
through the existing in-memory relay with the still as fallback. Frames
and manifests are pinned to each camera's own path on the agency hosts.

CCTV_VEGVESEN_ENABLED=0 disables the pack, CCTV_VEGVESEN_MAX_SOURCES
caps it (nearest the largest cities first) and CCTV_VEGVESEN_VIDEO=0
keeps stills only. Attributed under NLOD 2.0.
