fix: prevent phone input number from being hidden behind keyboard (#5124

)

### Description

Uses the keyboard aware scroll view to prevent the keyboard from
obscuring the 'continue' button when the phone number input is selected.
Also sets SafeAreaView to `height: '100%'` instead of `flexGrow: 1` to
prevent continue buttons from render off screen when large fonts are
used as this can prevent users from advancing to the next screen.
