fix(opencloud): remove external LDAP config, use IDM for user storage

Graph service was routing auto-provisioning to external OpenLDAP which lacks
the OpenCloud schema (openCloudUUID: attribute type undefined). The explicit
graph.identity.ldap, users.drivers.ldap, and groups.drivers.ldap sections in
opencloud.yaml overrode the default IDM LDAP, causing user creation to fail.

Remove all external LDAP sections so Graph/Users/Groups default to IDM's
internal LDAP, which has the full OpenCloud schema. IDM is already running.
