🙌 a11y: Searchbar/Conversations List Focus (#7096)

* chore: remove redundancy of useSetRecoilState and useRecoilValue with useRecoilState in SearchBar

* refactor: remove unnecessary focus effect on text area in ChatForm

* refactor: improve searchbar and clear search button accessibility

* fix: add tabIndex to Conversations component for improved accessibility, moves focus directly conversation items

* style: adjust margin in Header component for improved layout symmetry with Nav

* chore: imports order
