[Order Form] Use `TextInputAutocapitalization.words` or UIKit equivalent to capitalize first letter of each word in an address

[joshheald]

When editing or adding a customer address in the Order Form, it would be convenient for the user if the keyboard switched to capitals for the first letter of each new word, as this is common behaviour for addresses.

There may be a locale-aware address format mask available, which would be even better.
