Update store badges to use configured colors from the administration module

Modify the Dashboard component to dynamically set the background and border colors of participating store badges based on the `group.color` property, enhancing visual consistency with store configurations. The `selectedStoreId` prop is used to apply a ring effect to the currently active store.
