feat(seed): per-scene loop video + thumbnail for every scene

Browse Source 
Each scene now carries both a still (content.scenes.image) AND a short ~1.5s LOOP
video (content.scenes.demo), so the studio scene cards show a looping preview, not
a static swatch.

- LOOP_SCENES = {CharacterStory, LogoMotion3D}: their scenes get a dedicated
  per-scene loop ({tid}-{asp}-c{n}-loop.mp4 / {tid}-{asp}-loop.mp4); other
  templates fall back to their full preview MP4.
- Renders 42 loops: LogoMotion3D ×3 (frames 30–74) + CharacterStory 13 scenes ×3
  aspects (frames (n-1)*90+20 … +64), each a 45-frame / 1.5s clip mid-scene.
- Seed sets image + snapshot_url + demo per scene; verified all 42 serve 200 and
  the DB wires each scene to its own still + loop.
