feat(landing): rebuild as Next.js app with live product mocks

Replaces the static HTML page with a Next.js 15 + Tailwind v4 + Motion
app. The hero renders the dashboard itself - live tiles, ticking clock,
wandering metrics, pulsing status dots - instead of screenshots. Adds a
playable four-renderer switcher (bento/cards/index/console) with layout
animations, live monitor/domain/system mocks, and a cycling alert feed.

Vercel project dash is now git-connected with root dir landing/; pushes
deploy automatically. Canonical alias: dash-homelab.vercel.app.
