chore(auth): OtOpcUa unify dev LDAP base DN to dc=zb,dc=local (Task 1.6)

Replace all dev-directory dc=lmxopcua,dc=local references with dc=zb,dc=local
across LdapOptions default, integration harness overrides, docker-compose LDAP_ROOT,
AclEdit placeholder DN, and dev/smoke-test docs. CN/OU prefixes preserved.
