Add News Pagination and Filtering Controls

Back:
Development of backend API filtering capabilities allowing users to filter news content by impact levels (low, medium, high) and currency pairs for more targeted news consumption. The backend must provide RESTful endpoints supporting multiple filter combinations and efficient query processing to handle high-volume news data while maintaining optimal response times for the frontend pagination system.

Front:
Implementation of pagination system limiting news display to 5 items per page, plus integration of filtering controls for impact levels (low, medium, high) and currency selection. This frontend enhancement improves user experience by reducing information overload and enabling targeted news consumption, consuming new backend filtering APIs and providing intuitive UI controls for traders to customize their news feed according to trading preferences and risk tolerance.
