svc-db-openldap: make LDIF import idempotent, unify container var, and tidy role

- Add handlers/main.yml to load memberof/refint modules and import groups via docker exec
- Use OPENLDAP_CONTAINER consistently (replace OPENLDAP_NAME)
- Rename tasks/ldifs_creation.yml -> tasks/_ldifs_creation.yml and update includes
- Drop default param from get_app_conf calls; add explicit meta: flush_handlers
- docker-compose: honor OPENLDAP_NETWORK_EXPOSE_LOCAL | bool; minor formatting
- env template: formatting/comments consistency
- Remove unused 01_rbac_group.ldif.j2; rename 02_rbac_roles -> 01_rbac_roles and fix filter to LDAP
- vars: rename OPENLDAP_NAME -> OPENLDAP_CONTAINER; prune LDIF schema type
