feat(website): book-a-demo & status pages, expand roadmap/contact

- /demo: book-a-demo page with a what-to-expect column + a form that
  composes a prefilled email to info@dezky.eu (interim, no backend); built
  to swap for a self-hosted scheduler later. Wire every "Book a demo" CTA
  (nav, hero, pricing, the previously-dead final-CTA button, and the
  contact/partners/migration/coming-soon CTAs) to /demo.
- /status: manually-maintained system-status page (overall banner,
  per-service rows, incident history). Live modules operational; Video/Chat
  marked coming soon.
- Roadmap: expand the board (5 items/column) + a "the bigger picture"
  themes grid + a "suggest a feature" CTA + a directional-timelines note.
- Contact: purpose-specific channels (info@ / legal@ / privacy@), a
  response-time note, and a company + "see it live" demo block.
- Drop /status from the [slug].vue stub map; tidy now-unused imports.
