refactor(item_list): Refactor `ItemsList` component to improve readability and reuse.

- Extracted item selection toggle logic into a dedicated `toggle_selection` function.
- Simplified access to item properties in views by using references (`&`).
- Improved code clarity and maintainability by reducing inline complexity.
