Add remote Caddy support — generate snippet files when Caddy is on another host

Browse Source 
New site config key: CADDY_REMOTE_HOST (set via 'sudo ./setup.sh configure').
When set, configure_caddy_for_service operates in "remote" mode instead of
writing to a local Caddyfile:
- Upstream uses CADDY_REMOTE_HOST:PORT (host IP, not container name)
- Snippet saved to ~/docker/caddy-snippets/<subdomain>.caddy
- User is shown scp/rsync commands to copy it to the Caddy machine

Three modes in configure_caddy_for_service (lib/common.sh and inline stubs):
  local:  ~/docker/caddy/ exists → write Caddyfile + reload (existing behavior)
  remote: CADDY_REMOTE_HOST set → save snippet, print copy instructions
  none:   neither configured → silent return (unchanged)

All 31 service standalone bootstrap stubs updated with the new logic.
CADDY_REMOTE_HOST global added to all 42 standalone bootstrap sections.
setup.sh configure now prompts for CADDY_REMOTE_HOST with a clear explanation.
wolf.sh: add missing stubs (configure_caddy_for_service, write_readme,
  prompt_yn, ensure_docker_dir_ownership) and the Authelia/Caddy/start calls
  that were missing from the install function.
