chore(catalog): carry the Cuprate store entry into the frontend public catalog

generate-app-catalog.py only updates entries that already exist in each
catalog file, so the hand-curated cuprate entry (added to
app-catalog/catalog.json with 7b88ba59) never propagated to
neode-ui/public/catalog.json — the sync's field-bumps did, the new entry
did not. Both catalogs now carry identical 31-entry lists (verified
content-equal), so the browser-side store copy and the curated one agree.
