Add website analytics
A Tianji-style Websites section: a small tracking script, a public collection endpoint, and a page per website with visitors, page views, visits, bounce rate, a chart and top lists for pages, referrers, browsers, systems, devices, countries, languages and events. No cookies and no stored IP address or user agent. SANDBAR_TRUST_PROXY makes the client address come from the proxy. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
