R-498: the app page's first steps name the household's address, not wiki.DOMAIN

AppInfo.WithAddress fills the catalog placeholder (<label>.DOMAIN -> the
effective subdomain + customer domain, bare DOMAIN -> the domain) on a
copy; appDetailHandler applies it. Pinned per catalog template (both
languages) and on the rendered page.
