feat(frontend): open cluster files in the full viewer for comparison
deploy / deploy (push) Successful in 18s

The lightbox only showed the preview image, but dedup decisions need the
metadata — date, tags, EXIF — to choose a survivor. Replace it with the same
FileViewer the files page uses, mounted as a full-screen overlay with prev/
next wired across the cluster's files. A review toggle made in the viewer is
mirrored back into the cluster list. Drops the now-superseded PreviewLightbox.
