FIXED - Move page transition from template to persistent layout so it animates

A template.tsx is re-created on every navigation, resetting AnimatePresence
so neither enter nor exit ran. Move the transition into a PageTransition
client component rendered in the persistent (site) layout, so AnimatePresence
survives navigations and the old page animates out before the new one in.
