feat: Add MinIO and graph database status handling with localization updates

- Introduced a new boolean field for MinIO status in the system info API response.
- Updated localization files in English, Russian, and Chinese to include warnings and instructions related to MinIO and graph database configurations.
- Enhanced the KBAdvancedSettings component to display alerts and disable options based on the status of MinIO and graph database.
- Implemented logic to check system status on component mount and adjust settings accordingly.
