Subject: [PATCH] feat(monitoring): add uptime monitoring via Blackbox Exporter

- scripts/check-status.sh: parallel HTTP check aller mana.how Domains aus cloudflared-config.yml
- docker/blackbox/blackbox.yml: Blackbox Exporter Config (http_2xx, http_health Module)
- docker-compose.macmini.yml: blackbox-exporter Container (Port 9115, 32MB RAM)
- docker/prometheus/prometheus.yml: 4 Scrape-Jobs (blackbox-web, blackbox-api, blackbox-infra, blackbox-gpu)
- docker/prometheus/alerts.yml: 5 Alert-Regeln (WebAppDown, APIDown, InfraToolDown, GPUServiceDown, SlowHTTPResponse)
- docker/grafana/dashboards/uptime.json: Grafana Uptime-Dashboard mit Status-Tables und Verlauf
- package.json: check:status Script
