Enhance EditorManager and TestManager with improved ROM handling and testing features

- Added logging to track ROM changes in EditorManager, ensuring TestManager is updated with the current ROM.
- Implemented real-time ROM status checks in TestManager for better debugging and user feedback.
- Introduced a dialog for creating and managing test ROM sessions, allowing users to open modified ROMs easily.
- Enhanced the testing framework with methods for creating test ROM copies and generating filenames with timestamps.
- Improved the overall user interface of the TestManager, including a more informative dashboard and session management options.
