Groundwork for Enhance "Animate" (#208): a video made from a photo.
- Version linking reads the XMP link from MP4 / MOV too (top-level uuid box
with the XMP UUID, mdat seeked over), at ingest and on Enhance approve.
- New kind `animated`, a derived clip (CLIP_KINDS): hidden behind the photo
like a version, but not counted in photo_version_counts / version_count,
never a display choice (400 clip_not_displayable), and listed as `clips`
in GET /image/versions. Approve returns the clip entry.
- Templates whose imageapi:save is ImageApiSaveVideoVersion report
output "video" in /enhance/templates (no enhance.toml change). Previews
already relay ComfyUI's content type (video/mp4).
