Subject: fix: submenu as expanding second row inside header glass

Replace floating dropdown box with a full-width centered second row that
expands the existing frosted header panel on hover/focus. Project pages in
the submenu fall back to page title when no menu name is set. Same label
fallback applied to mobile overlay children.
