feat: Implement lazy loading for dungeon rooms and refactor room graphics handling

- Introduced lazy loading for room data to optimize performance and reduce initial load times.
- Updated DungeonEditor and DungeonRoomLoader to handle room graphics rendering directly from room objects.
- Refactored methods to accept room references instead of IDs for better clarity and type safety.
- Enhanced tab management in the DungeonEditor UI for improved user experience.
