fix(infra): update status page, prometheus, and cloudflared for unified app

All web app subdomains (chat.mana.how, todo.mana.how, etc.) were removed
when the unified app launched, but monitoring configs still referenced them.
Update blackbox targets to use mana.how/route URLs, remove stale API backend
routes from cloudflared, clean up CORS origins, and fix status page generator
to handle route-based URLs.
