Code Review

This pull request replaces the v-select component with v-autocomplete in ConfigItemRenderer.vue for list-type configurations and adds the clear-on-select property. A review comment suggests further improving the user interface by adding the closable-chips prop to the multi-select autocomplete component, allowing users to remove selected items more easily.

When using multiple selection with chips, it is highly recommended to include the closable-chips prop. This allows users to remove selected items directly by clicking the 'x' on the chip, which is much more intuitive and efficient than having to open the menu and find the item to deselect it, especially when the list of options is long.
