fix(opencloud): load OpenCloud LDAP schema into OpenLDAP on startup

User creation failed with "openCloudUUID: attribute type undefined" because
OpenLDAP was missing the OpenCloud schema (OIDs under 1.3.6.1.4.1.63016).

Changes:
- Add opencloud-ldap-schema.yaml ConfigMap with the official OpenCloud LDAP
  schema defining openCloudUUID, openCloudUser, openCloudExternalIdentity,
  openCloudUserEnabled, openCloudUserType, openCloudLastSignInTimestamp
- Mount the ConfigMap into the OpenLDAP pod
- Add lifecycle postStart hook to load schema via ldapadd -Y EXTERNAL -H ldapi:///
  (idempotent: skips if already loaded)
- Re-exclude IDM in OpenCloud deployment (external LDAP handles user storage)
