Extract Footer component from PromptField and streamline Tabs rendering

- extract footer into a spearate component
- this should be params variable [Fragment] dont destructure
- when there is only a single tab, its dot should be shown
- when prompt is empty and there is only a single tab, don't replace filled dot with 'close' icon on hover
