Add Authelia SSO prompt to js99er, magicmirror, wolf-pair

These services have no built-in auth. Per CLAUDE.md they should check for
Authelia and offer to protect them with SSO before calling
configure_caddy_for_service. Adds the standard prompt_yn + import authelia
extra block pattern to all three.
