Add TTL Cache to GET news endpoint 9 days ago

AI Summary: This issue proposes implementing a Time-To-Live (TTL) cache for the `GET /news` endpoint to reduce calls to the `yfinance` client and improve response times. The implementation may require custom logic for cache keys, potentially using tuples to store and retrieve news items based on request parameters. Key files to be modified include the news router and service, application settings, and dependencies.

Complexity: 3/5
