feat(website): add Nuxt 4 marketing landing page

New standalone apps/website (Nuxt 4) serving the public marketing site at
dezky.local / www.dezky.local. The customer portal moves off the root domain
to app.dezky.local only.

Landing page ported from the Dezky design handoff: light theme, Danish
default, hero variant A, with a working da/en toggle. Self-contained colour
system threaded through components (utils/landingTokens.ts), full bilingual
copy (utils/landingCopy.ts), and shared state (composables/useLanding.ts).
Sections live under components/landing/* with the Node logo under
components/brand/*.

Wired into docker-compose (website service, volume, Traefik labels, network
aliases) and bootstrap.sh (hosts list + service URLs).

+// Dezky "Node" mark — a lowercase d (donut style) inside a squircle, with a
+// corner node-dot. Geometry is the locked set from the brand handoff
+// (logos.jsx NodeMark + LOCKED). The squircle paints in `fg`; the letterform
+// and dot paint in `accent` (electric chartreuse) — the design's intent.
