feat(client): remove Overview item from space sidebar

Drop the Overview home link that sat between the space switcher and
the Pages section in the authenticated space sidebar. Remove the JSX
block and clean up the now-unused imports (UnstyledButton, IconHome,
useLocation, getSpaceUrl) and the local `location` variable.
