Add AllMarkSeen Functionality to Notification System

- Introduced the AllMarkSeen method in the notification service to mark all notifications as seen for a user, enhancing user experience by allowing bulk actions on notifications.
- Implemented the PublicAllMarkSeen handler to handle HTTP requests for marking all notifications as seen, ensuring proper request validation and response handling.
- Updated the notification client and SDK to support the new AllMarkSeen functionality, improving the overall API capabilities.
- Enhanced API documentation with Swagger comments for the new endpoint, ensuring clarity for API consumers.
