feat: site name config, host facts, and service ports/repos in the directory seed

- CFG_SITE_NAME in setup.env (below CFG_DOMAIN, default "local") names
  the directory site; slug site_<name> matches ldap-client's parentSlug
  convention so joined Linux hosts land under the same site. Wired
  through sso-secrets.js stack.siteName.
- setup.sh collects host facts ON THE HOST (hostname, IP, default-route
  MAC, OS pretty-name, kernel — same collection as ldap-client/index.sh)
  and passes them into the bootstrap exec env; the stack host is now
  registered as host_<hostname> with that metadata (subType linux).
- Services carry their internal port and git repo in metadata
  (sso-manager 3001, proxy 3000, openldap 389/ext 636, openresty 443),
  using the metadata keys the directory UI natively displays.
- ensure() now adopts resources from the earlier seed layout (alt slugs
  'stack-host' / domain-slug site) and back-fills missing seed metadata
  via a metadata-only PUT — operator-set values are never overwritten.

Verified against a live app: old-layout resources are adopted and
back-filled (no duplicates), fresh seed creates the full graph, and a
second pass changes nothing.
