feat: Improve selected rows data management in TabsWidget and SplitPanelLayoutComponent

- Refactored TabsWidget to manage local selected rows data, enhancing responsiveness to user interactions.
- Introduced a new callback for handling selected rows changes, ensuring updates are reflected in both local and parent states.
- Updated SplitPanelLayoutComponent to share selected rows data between tabs and buttons, improving data consistency across components.
- Enhanced overall user experience by ensuring immediate recognition of selection changes within the tabbed interface.
