Adds the remaining monitor types: a systeminformation-backed system widget (single-flight cached so multiple widgets don't force concurrent samples), an http widget with per-widget consecutive- failure tracking, and a traefik widget that reads router/entrypoint/ middleware status from Traefik's own API. Also adds opt-in label-based docker auto-discovery (discovery.docker in config.yml): containers carrying traefik.enable=true are turned into docker widgets in a synthetic "Discovered" group, re-scanned on a timer and whenever config.yml changes, with manual widgets always taking precedence over a discovered one for the same container. Fixes a real bug surfaced while testing discovery: Next's App Router bundles app/** through its own compiler pass, separate from server.ts (run directly via tsx), so configStore/effectiveConfigStore were silently instantiated twice - one instance watched and updated by server.ts, another frozen instance read by SSR. Live config edits were never reflected on page load without a full process restart. Both stores now key their singleton off globalThis, which both module graphs share within the same process. Verified against a real Traefik v3 container (API-driven router list, ping-based http check) and a labeled nginx container (auto-discovery), including that a config.yml edit now shows up in a fresh page load without restarting the server, in both dev and the production build.
