Enhance admin maintenance functionality with new endpoints and response types

- Added new DELETE endpoints for managing audit logs and disabled apps in the admin maintenance section.
- Updated existing endpoint for closed tickets to use a unified response type, `MaintenanceCleanupResponseDto`.
- Enhanced API documentation to reflect the new operations and their expected request/response formats.
- Improved frontend integration with new functions for deleting old audit logs and disabled apps, including user confirmation prompts.
- Added localization support for new maintenance actions in both Russian and English.
