Referral badge across storefronts and store selection page

Referral badge across storefronts

A configurable referral badge that customers can use to share the store and earn credit. Ships in both legacy storefronts (admin toggle) and AI-built stores (injected automatically, self-contained, no theme edits required to opt in).

Store selection page

Operators managing multiple stores get a dedicated selection page instead of a dropdown, with store search and recent-store memory.
