Use config_headlineFontFamily for password screens.

These screens are used whenever setting or confirming the
lockscreen PIN or password. Set them to a consistent textSize (24sp)
and a consistent fontFamily.

Would have set the fontFamily in the style, but unfortunately
setInputType is called on the TextViews after inflation which blows
away the fontFamily. Instead, we set it in code right after that
call.
