feat: Implement Jump-to Functionality for Cross-Editor Navigation

- Added JumpToDungeonRoom and JumpToOverworldMap methods to facilitate quick navigation between dungeon and overworld editors.
- Introduced SwitchToEditor method to manage editor tab activation based on the selected editor type.
- Enhanced DungeonEditorV2 with room and entrance selection capabilities, improving user experience and workflow efficiency.
- Updated header files to declare new methods and ensure proper integration within the editor management system.
