feat: add first wutta-based master, for PersonView

still opt-in-only at this point, the traditional tailbone-native
master is used by default.

new wutta master is not feature complete yet.  but at least things
seem to render and form posts work okay..

when enabled, this uses a "completely" wutta-based stack for the view,
grid and forms.  but the underlying DB is of course rattail, and the
templates are still traditional/tailbone.
