Add $VOICEBOX token page, blog, and cloud/pricing pages

- /token: dedicated page with on-chain transparency (liquidity lock +
  buyback/burns), holder utility, official-token clarity, and FAQ. The
  landing now shows a teaser linking to it; navbar + footer repointed
  from pump.fun to /token.
- /blog: file-based markdown blog (gray-matter + marked) with per-post
  Open Graph images; first post "Why Voicebox has a token".
- /cloud: end-to-end encrypted backup & sync product page.
- /pricing: Local / Cloud / Studio tiers with a monthly/annual toggle;
  $VOICEBOX holders get Cloud free.
- Add Testimonials section to the landing.
- Navbar: remove API/Download, add Pricing/Blog, fix center-nav spacing.
- docker-compose: host port 17493->17600 for local dev coexistence.
