Enhance mission management and gameplay interactions

- Introduce detailed logging for unit deaths during damage and chain damage events in GameLoop, improving feedback on combat outcomes.
- Update MissionManager to store completed mission details, ensuring procedural missions are accurately tracked and displayed in the UI.
- Modify TurnSystem to handle unit deaths from environmental hazards, enhancing gameplay realism and unit management.
- Improve MissionBoard to include completed missions that are no longer in the registry, ensuring players have visibility into past achievements.
- Add tests to validate new features and ensure integration with existing systems, enhancing overall game reliability.
