Wires the per-scene loop video all the way to the scene card:
- studio-svc: SavedSceneResponse now includes Demo (was stored + copied but never
serialized); MapSceneResponse passes s.Demo.
- Scene type gains image?/demo?; parseScene reads them from the loaded scene data.
- SceneThumbnailBlock shows scene.image as the still and plays scene.demo (muted,
looped) on hover, resetting on mouse-leave.
Existing projects backfilled (saved_scenes.image/demo from content.scenes). Both
services rebuilt + deployed.
