feat(remotion): +LogoMotion3D template (Tech/3D cinematic logo reveal)

First template built through the new flow (brief → quality-gate approval → build →
seed → deploy). Tech/3D logo motion: a 3D metallic card + radial light rays + lens
flare + bloom (genuine @remotion/three), with the user's uploaded logo composited
on the card as a reliable HTML <Img> (renders any SVG/PNG/data-URI; static camera
keeps it aligned), brand text + tagline, grain. Falls back to a branded play-mark
when no logo is set. Re-flows across 16:9/1:1/9:16.

- LogoMotion3D.tsx registered per aspect in Root.tsx.
- Seeded as fr-logo-motion-3d: text fields (brandText, tagline) + a logoUrl image
  upload field + the dark-tech palette (light text) + per-aspect previews.
- 3 thumbnails + 3 preview MP4s rendered, deployed; detail page + assets serve 200.
