Theseus 0.3.123 (cont'd): catalog visible by default, "+ Show more" at the bottom

The curated catalog was hidden behind the "+ Add search engine" button at
the top-right of the header, which buried the common case (pick one of
the five curated options) behind an extra click. Flipped the layout so
the curated catalog paints inline right below the Enabled list, and the
"+ Show more" button lives at the bottom — opens the Discover-more bank
and the custom-URL form. Same change on the AI engines page.
