fix: register the arrivals group in the lab list

Catalog.groups is a hard-coded list and did not include the arrivals catalog,
so the five new modules (112705 probe/fire, 112621 probe/fire, 84636) and
kern.ipc.lifecycle were counted in Catalog.all but invisible in the POCs tab.
Add a localized 新收录 / New arrivals group at the top; simulator screenshot
confirms all six entries render. Build 6.
