Add news feature with CRUD operations and real-time notifications

- Implemented news management functionality, allowing admins to create, read, update, and delete news posts. - Introduced a new SignalR event for broadcasting news updates to all connected clients. - Updated API documentation to include new endpoints for news management. - Enhanced frontend with a dedicated news page and admin interface for managing news posts. - Added necessary localization for news-related terms in both Russian and English.
