site_name and site_description are shop identity, not theme concerns.
They now live in the Settings table as first-class settings with their
own assigns (@site_name, @site_description) piped through hooks and
plugs. The setup wizard writes site_name on account creation, and the
theme editor reads/writes via Settings.put_setting. Removed the
"configure your shop" checklist item since currency/country aren't
built yet. Also adds shop name field to setup wizard step 1.
