Joomla: Add LDAP autocreate plugin support

- Introduced autocreate_users feature flag in config/main.yml
- Added ldapautocreate.php and ldapautocreate.xml plugin files
- Implemented tasks/01_ldap_files.yml for plugin deployment
- Added tasks/05_ldap.yml to configure LDAP plugin and register ldapautocreate
- Renamed tasks for better structure (01→02, 02→03, etc.)
- Updated cli-ldap.php.j2 for clean parameter handling
- Mounted ldapautocreate plugin via docker-compose.yml.j2
- Extended vars/main.yml with LDAP autocreate configuration
