[FIX] website_sale_delivery: Compute summary total amount on delivery update

Issue

	- Connect on smartphone (or use chrome debug mode to switch to mobile view)
	- Install "Ecommerce" module
	- Add a delivery method D with a price on product P
	  and publish it
	- Go to shop and add product P to your cart
	- Go to payment and switch delivery method

	Total amount above the summary is not updated.

Cause

	Update is done on JS when delivery method is changed.
	No targeting Total Amount in summary head card (seen only on small device).

Solution

	Add ID on Total Amount in summary head card element and update it with JS
	in same time as other fields (taxes, total, ...).
