Accept US territory phone numbers in isValidUSPhone validation

The isValidUSPhone function previously required region code to be
exactly 'US', which rejected valid phone numbers from US territories
that share the +1 country code but have their own ISO region codes
(e.g., PR for Puerto Rico, GU for Guam). This caused users in
Puerto Rico to see "Please enter a complete phone number" errors
when trying to add their phone for bank account verification.
