Release 1.2.0: adopt shared @simpleworkjs/* packages; fix directory envelope drift

Rewire onto the shared @simpleworkjs/oidc-client, /directory-schema, /ldap, and
/app-stack packages (deleting the byte-identical local forks). utils/access.js
now fetches reachable hosts through the shared directory client, which
validates the {results} envelope and treats envelope drift as a failed group
rather than silently returning []. models/user_ldap.js is a thin wrapper over
createLdapClient (loose TLS default preserved). build_info moves to utils/ with
the shared {buildVersion,buildHash,buildYear} shape. Align ldapts ^8.1.8 and
redis ^6.1.0. Lockfile regenerated from the registry (no file:/link:).
