Redirect to login page for review list/detail views if not logged in

This avoids showing a 403 error when a user clicks on a review link in
the layer submission notification email but hasn't logged in yet.

Also protect the review list view with a permission check; it's not that
it's sensitive, but we should be consistent with the detail here.
