feat: Enhance editor card management and shortcut functionality

- Introduced new shortcut categories for graphics, screen, and sprite editors, improving accessibility and organization.
- Updated DungeonEditorV2 and other editor classes to register cards with the EditorCardManager, allowing for better control and visibility management.
- Refactored shortcut registration for dungeon, graphics, screen, and sprite editors, ensuring consistent user experience across the application.
- Improved initialization processes to handle dynamic card visibility and shortcuts effectively.
