fix(registry): align timeline IDs and regenerate catalog index

- Fix timeline_id_mismatch on all 15 caption components: __timelines key
  now matches data-composition-id (e.g. "caption-clip-wipe" not "clip-wipe")
- Regenerate docs/public/catalog-index.json with 15 new caption entries
- Add "Captions" group mapping to generate-catalog-pages.ts (priority 0)
- Regenerate docs.json nav and mdx pages via the catalog script
- Upload docs preview videos to docs/images CDN path
