fix: pass redirectTo between login and sign up

This patch updates the login and sign up routes to forward their
`redirectTo` search parameter when navigating between the two. That way,
users can click the "No account? Sign up here" link and still be
redirected to their ultimate destination if applicable.

This patch also does some minor import refactoring (put the `type`
inside the `import` statement).
