Fix the follow-up review findings in import, layers, startup and engines

- KML/KMZ import: a per-file canvas budget and cache for ground overlays,
  limits on rings and vertices of raised polygons, overlays across 360° and
  near the poles, degenerate holes, polar and single-latitude fills,
  absolute overlays at their altitude, overlay order by drawOrder as on
  Cesium, and pins on tiles keep their measured height.
- Points on the surface: OSM Places and Street Level cones share the
  surface sampler and sit on the terrain before they are measured, within
  a sampling budget per pass; Cockpit's contact-dot bank keeps the dot
  atlas, and a failed fleet model loads again after a pause.
- Startup: the loading screen lifts after the share-link view is restored,
  the retry screen names the failed engine and takes focus, and the
  fallback toast stays for 6 s.
- Engines: an engine switch lands a running camera flight at its
  destination (camera.completeFlight on both engines), the sighting card
  leaves focus on the engine picker after a switch, and a Cesium model
  error stays with the instance that failed.
- The MCP panel builds again: its wind-mesh alias resolves to the stub.
- QA: the wildlife switch waits for the camera to rest, GBFS --w2 says it
  needs the dev server, and test fixtures are shared instead of copied.
