hetzner-admin: stop/start individual services, shown as STOPPED on status page

- run-command.sh: services / stop <name> / start <name> for app and infra
  stacks (not caddy, hetzner-admin, status). Stopped names go to
  status/stopped.txt (gitignored).
- status: a stopped service that does not respond is STOPPED (gray),
  excluded from uptime and DOWN alerts. If it responds it is UP as usual.
- Infra deploy.sh skips stopped stacks; app repo pushes clear the flag.
- claude-code@.service: Restart=on-failure, and restart-sessions.sh restarts
  one unit at a time, to avoid the tmux "server exited unexpectedly" race.
