feat(versions): add base filter toggle UI and styling

Add CSS classes and JavaScript logic for the base filter toggle button in the versions toolbar. The filter allows users to switch between showing all versions or only versions matching the current base model. Includes styling for different states (active, hover, disabled) and accessibility features like screen reader support.
