- Updated Store interface to include methods for managing maintenances.
- Modified API functions to support pagination for heartbeat history and added CRUD operations for maintenances.
- Enhanced types to include paginated responses and initial log entries.
- Implemented maintenance management UI in the admin panel with create, edit, and delete functionalities.
- Updated service detail page to display paginated heartbeat history and improved chart rendering.
- Refactored status page to accommodate new data structures and ensure consistent data handling.
