Remove non-functional Joomla LDAP integration

- Disabled LDAP feature flag (set to false by default, with comment)
- Removed ldapautocreate plugin (PHP + XML)
- Deleted LDAP helper tasks (01_ldap_files.yml, 05_ldap.yml, 07_diagnose.yml)
- Deleted LDAP CLI helper scripts (cli.php, diagnose.php, plugins.php, auth-trace.php)
- Removed LDAP configuration variables from vars/main.yml
- Removed LDAP environment variables from env.j2
- Removed LDAP-specific mounts from docker-compose.yml.j2
- Dropped php-ldap installation from Dockerfile
- Renamed task files for consistent numbering (02->01_install, 03->02_debug, 04->03_patch, 06->04_assert)

Reason: LDAP integration was removed because it was not functional.
