Add a way for non-super-admin users to view orders that they cannot edit

[smellsblue]

Currently, if a user cannot edit it, clicking the order redirects them back to the orders page. Perhaps the controller should look something like this:

  def edit
    @order = Order.includes(order_details: :item).find(params[:id])

    if current_user.can_edit_order?(@order)
      if Rails.root.join("app/views/orders/status/#{@order.status}.html.erb").exist?
        render "orders/status/#{@order.status}"
      end
    elsif current_user.can_view_order?(@order)
      render "orders/show"
    else
      redirect_to orders_path
    end
  end
