Swap the pill navigation for a macOS-style dock as the primary nav and a
slim top menu bar for utilities:
- components/ui/dock.tsx: Magic UI Dock/DockIcon (magnification via
useSpring/useTransform), ported to the project's framer-motion.
- components/layout/site-dock.tsx: bottom dock with the logo as the first
icon, each item a real next/link (SEO preserved, active state from the
pathname), monochrome squircle tiles, hover tooltips and a "soon" badge
for Products; top menu bar keeps locale/sound/theme/admin + a live clock.
- (site)/layout.tsx: render SiteDock instead of SiteHeader.
Home bento grid and all page content are unchanged.
