## Major Architecture Improvements
- Refactored to use Drupal's core configuration system instead of custom PHP data files
- Implemented configuration event subscribers for seamless integration with config:export/import workflows
- Added robust configuration storage naming convention for predictable deployments
## Removed Components
- Removed deprecated ConfigPagesHandler service in favor of ConfigPagesExportManager
- Eliminated unnecessary post_update hooks (configuration is now handled via event subscribers)
