fix: LDAP enrollment uses localhost (not the public domain); align SSH access groups; roll up ldap-client v1.24.0 (v1.38.0)

- setup.sh: ldap_host defaults to localhost (the public sso.<domain> can't reach
  the 389/636 LDAP ports through NAT); overridable via CFG_LDAPS_HOST
- ldap.vars access groups + ldap-client sssd filter now reference the SSO group
  model (site_<loc>_hosts_access, site_<loc>_host_<host>_access, god_admin)
- GROUPS.md §5/§8 updated to the corrected naming
- gitlink: ldap-client ebaac18 (v1.24.0)

+### Fixed
+- **LDAP enrollment no longer reaches for the public domain** — `setup.sh` generated `ldap.vars` with `ldap_host` defaulting to the public SSO host (`sso.<domain>`), which the NAT/firewall blocks on the LDAP ports (389/636). It now defaults to `localhost` (the LDAP server is co-located on the stack host; `ldap_tls_reqcert=never` makes this safe), overridable with `CFG_LDAPS_HOST` for an internal hostname/IP.
+- **SSH access groups match the SSO group model** (ldap-client v1.24.0) — the generated `sssd.conf` access filter and `ldap-ssh-key.sh` referenced the legacy names (`<location>_access`, `app_super_admin`); they now use `site_<location>_hosts_access` (all-hosts aggregate), `site_<location>_host_<hostname>_access`, and `god_admin`. GROUPS.md §8's example updated to match.

 A host should import its **own** resource groups (plus any explicitly granted
 ones). Because the schema is predictable, `ldap-client` can generate the per-host
 `ldap_group_search_filter` from the enrolled host's identity, e.g. a host `web01`
