docs(legal): print the full US business address on the site

Stripe flagged the account under Visa 1.5.1.2 and Mastercard 5.5/5.6:
the location stated on the site has to match the Stripe account. The
legal pages only said "Wyoming, United States" and the footer said
nothing at all. Both now carry the same address Stripe has on file.
