HeaderZone and FooterZone are absent from componentResolver (so they can
never be deserialized/rendered) and are not imported by PageContext,
Canvas, or any other live code -- verified via repo-wide grep returning
only their own self-references. The site-wide header/footer feature uses
Container with tag="header"/"footer", not these zone wrappers. Deleted.
