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.
