feat(state_511_atis_cameras): Castle Rock 511 traffic cameras telemetry (v0.9.6)

New CENTRAL_TRAFFIC_CAMERAS stream + state_511_atis_cameras adapter. Telemetry
half of Castle Rock (events shipped in v0.9.2). Each Idaho camera -> one
telemetry event on /telemetry; detail drawer renders <img> direct from the
source (no blob storage / proxy in Central -- URL only).

supervisor + gui + ARCHIVE restart (NEW event-bearing stream
central.traffic_cameras.>). Ships disabled; public-unauth (no api key). Idaho only.

- Full camera list via POST /List/GetData/Cameras (DataTables), PAGINATED at
  100/page (Idaho ~455 = 5 pages). GetUserCameras was a red herring (4 default
  cams). The 100-row page cap also means v0.9.2 state_511_atis silently
  truncates its 114-row Construction layer -> separate v0.9.7 fix.
- Subject central.traffic_cameras.{state}.{camera_id}; category
  camera.state_511_atis_cameras -> GUI event_type "camera". data_class=telemetry.
- Per-UTC-day dedup {state}:cam:{id}:{YYYY-MM-DD}: one event per camera per day
  -- always shows today's cameras, no per-poll flooding, no retention
  coordination. Inherits the v0.9.1 dedup mixin.
- All sources included (Idaho511/ITDNET/RWIS/UDOT/ODOT/WYDOT/MTD border cameras);
  source surfaced in data + the drawer for provenance. WKT POINT (lon lat) -> geo.
- No upstream image-capture timestamp (lastUpdated is config-edit time); drawer
  shows no false "Captured" line. Cadence 600s. Severity 1 (telemetry).

Full suite: 829 passed, 1 skipped (central and unprivileged zvx, 3x each).
