feat: implement notifications and event history features

- Added Notification Service to manage project-level notifications, including creation, listing, marking as read, and dismissing notifications. - Introduced Event History Service to store and manage historical events, allowing for listing, retrieval, deletion, and replaying of events. - Integrated notifications into the server and UI, providing real-time updates for feature statuses and operations. - Enhanced sidebar and project switcher components to display unread notifications count. - Created dedicated views for managing notifications and event history, improving user experience and accessibility. These changes enhance the application's ability to inform users about important events and statuses, improving overall usability and responsiveness.
