Add status pages, ntfy alerts, and license-slot-checker repo

- status/: lightweight status checker (status.yyamashita.com, /api/status)
  with ntfy DOWN/recovered alerts after consecutive failures
- uptime-kuma/: Uptime Kuma at uptime.yyamashita.com
- hetzner-admin: authenticated /status page (status-app results + docker ps -a)
- ntfy/: self-hosted ntfy at ntfy.yyamashita.com (deny-all auth, install.sh
  creates admin user and status-app token)
- Caddyfile, DNS, post-receive hook, tests/check.sh, docs updated
- license-slot-checker: add to repos.txt, hook, and Claude sessions
