[bugfix]: list Open-H3-Regenerate-2K under Video upscale and count its cookbook card

The directory took the page's first tag, "Video to video", which taskLabel()
does not map, so the model fell back to "Text to video". Tag it "Video
upscale" and let that label map to the upscale group. Update the hardcoded
card counts for the added card and test the task filter and page route.
