refactor: Improve label toggling functionality in ScreenDesigner and enhance SelectedItemsDetailInputComponent

- Updated the label toggling logic in ScreenDesigner to allow toggling of labels for selected components or all components based on the current selection.
- Enhanced the SelectedItemsDetailInputComponent by implementing a caching mechanism for table columns and refining the logic for loading category options based on field groups.
- Introduced a new helper function to convert category codes to labels, improving the clarity and maintainability of the price calculation logic.
- Added support for determining the source table for field groups, facilitating better data management and retrieval.
