leaderboard: backfill tool for edit_diff.png stills in render bucket

One-time tool to close the gap for submissions evaluated before the eval
pipeline started writing edit_diff.png: lists the render bucket, finds every
<fixture>/edit_diff.webp lacking a sibling edit_diff.png, extracts frame 0
via cadgenbench.common.imaging.first_frame_png (the exact frame the pipeline
now saves), and uploads the still to the same bucket prefix. Idempotent
(skips existing stills); --dry-run lists without a token.
