feat: add /guestbook page with D1-backed entries and IP rate limiting

Visitors can leave a name + message (max 280 chars). Entries are stored
in Cloudflare D1, hashed-IP rate-limited to one entry per 24 hours.
Includes full theme support (scandinavian/hacker/space) and keyboard
navigation integration.
