feat(editor): enhance card-based editor functionality and streamline initialization

- Updated EditorManager to support new card-based editors, including Emulator, Hex, and Assembly editors.
- Added centralized registration of editor cards with EditorCardManager, improving visibility management.
- Implemented methods to retrieve editor types from categories and manage card visibility dynamically.
- Enhanced initialization processes for various editors to ensure proper card registration and default visibility settings.

Benefits:
- Improved user experience by organizing editor cards and providing quick access to new editor functionalities.
- Streamlined editor management, making it easier to switch between different editing contexts and enhancing overall workflow efficiency.
