refactor(editor): enhance UI coordination and menu management

- Updated EditorManager to include ShortcutManager in the UICoordinator initialization, improving UI responsiveness.
- Refactored menu handling in MenuOrchestrator to delegate more responsibilities to UICoordinator, streamlining the UI flow.
- Removed unused menu items and comments, clarifying the code structure and enhancing maintainability.

Benefits:
- Improves the organization of UI components, leading to a more efficient user experience.
- Enhances clarity in the codebase by reducing clutter and focusing on essential functionalities.
