Introduce server-rendered guestbook and moderation portal. Persist data in SQLite (better-sqlite3); add WebAuthn YubiKey admin auth, rate-limiting, spam heuristics, and sanitization. Switch Docker image to run Node/standalone Astro (remove nginx), update docker-compose, Dockerfile, astro.config, and package.json. Add .env.example, docs/guestbook.md, gitignore updates, layouts, API routes, and supporting lib/components/pages for the feature.
