feat: Enhance SplitPanelLayoutComponent with delete modal improvements

- Added a new state to manage the table name for the delete modal, allowing for more specific deletion handling based on the context of the item being deleted.
- Updated the delete button handler to accept an optional table name parameter, improving the flexibility of the delete functionality.
- Enhanced the delete confirmation logic to prioritize the specified table name when available, ensuring accurate deletion operations.
- Refactored related logic to maintain clarity and improve the overall user experience during item deletion in the split panel layout.
