🔒 Fix bare except clause to prevent catching system-level exceptions

[NoWon1]

🎯 What: Fixed a bare except: clause in Simulation/CancerInvasionSteppables.py.
⚠️ Risk: A bare except: clause can catch system-level exceptions like SystemExit and KeyboardInterrupt, making it difficult or impossible to stop the execution cleanly, which can lead to hanging processes or mask unintended termination signals.
🛡️ Solution: Replaced except: with except Exception: which ensures only standard runtime exceptions are caught, allowing system-level signals to pass through as intended.
