Added Registrations Report

Overview

A new Registrations Report is now available under Reports. It shows daily customer registrations, how many of those customers placed their first order, the first-order conversion rate, and first-order sales.

This gives merchants a clearer view of whether new customer registrations are turning into actual orders. It is especially useful when tracking campaigns, sign-up flows, and other customer acquisition efforts where the goal is not only more registrations, but also more revenue from newly acquired customers.
