Add 'business' profile type and category

Business accounts are cli profiles with businessAddress=True, so each connecting
customer gets their own group chat (handled via the existing chat UI) with an
optional welcome auto-reply. New BUSINESS_TYPES, a /business page + sidebar entry,
and a business variant of the create form. profile/chat pages route via a
_category helper. Adds business_test.py (customer connects -> lands in a business
group, not a direct contact) — passes.
