fix(hub): adjust no-group prompt and post-create wizard step

No-group home/explore message: when the hub offers no public groups,
drop the "browse public groups" invitation and just ask to be invited
by an admin. New home.invite_only key added to all ten catalogues.

Create-group wizard done step: reword the message to point at inviting
members, and send the button to the group's Settings tab (where the
invite form lives) instead of a stale /groups/<id> path that never
matched the router. The landing tab is a one-shot session hint, so the
usual per-user default-tab preference is left untouched.
