refactor: replace raw buttons with Button component in WidgetActions (#8973)

Fixes #8889

Replaces custom-styled `<button>` elements in WidgetActions.vue with the
shared Button component for better consistency with the design system.
Uses `variant="textonly"` with `size="unset"` to match the existing
dropdown menu item styling.
