Enhance EditorManager and TestManager with new ROM testing features and UI improvements

- Added new menu options in EditorManager for ROM analysis and testing, including data integrity checks and save/load testing.
- Updated TestManager to include enhanced logging for ROM state and new actions for refreshing the current ROM reference.
- Introduced a dedicated UI for displaying ROM test results and options for running tests on the currently loaded ROM.
- Improved the overall layout and organization of the testing dashboard for better user experience and accessibility.
