feat(editor): enhance screen editor with title screen and inventory item icon features

- Implemented title screen editing capabilities, including loading and rendering of title screen layers.
- Added inventory item icon management, allowing for the display and selection of item icons within the inventory menu.
- Updated the inventory creation process to ensure proper ROM loading and error handling.
- Introduced new canvas components for title screen and inventory item icons, improving the user interface for editing.

Benefits:
- Enhances the functionality of the screen editor, providing users with tools to edit title screens and manage inventory icons effectively.
- Improves user experience by ensuring robust error handling and visual feedback during inventory management.
