Handled Exception when Fetching Force by ID in StratconPanel

Added a try-catch block to handle errors when fetching a force by its ID in `StratconPanel.java`. This prevents the application from attempting to draw a force on the map if it fails to fetch the force data and logs an error message accordingly.
