Subject: [PATCH] feat: Update SplitPanelLayoutComponent to manage custom left
 selected data

- Initialized custom left selected data to an empty object when deselecting an item, ensuring a clean state for the right form.
- Passed the selected item to the custom left selected data when an item is selected, improving data handling in custom mode.
- Enhanced overall data management within the SplitPanelLayoutComponent for better user experience.
