Add write_readme, Caddy, and start prompt to wolf/homeassistant/js99er/minecraft

- wolf.sh: add Authelia SSO check, configure_caddy_for_service, write_readme,
  and prompt to start Wolf (it had none of these)
- homeassistant.sh: add write_readme with access URL and manage commands
- js99er.sh: add write_readme with access URL and manage commands
- minecraft.sh: add write_readme with manage and backup commands

Completes the service audit — all 49 services now have full interactive setup,
standalone bootstrap, and self-documenting README in the deploy directory.
