Estimate work needed to remove items from cart if they run out of stock

[RachL]

⚠️ Please use clockify code #12476 Flower Farms

Description

- As a: shopper
- On page: /cart/XXX and /checkout/XXX
- I want to be able to do:

if one of the items i've added to my cart becomes out of stock I see a generic message telling me my cart was updated.

Shopper can dismiss the message. It should appear on all shopfront pages when products have become unavailable.

Acceptance Criteria & Tests

The spike results need to give a clear solution in terms of tech solution. And an estimate of the amount of work needed. No development should be started at this stage.

This should already be happening when adding to cart. Code references:

• app/controllers/cart_controller.rb
• app/assets/javascripts/darkswarm/services/cart.js.coffee
• app/assets/javascripts/templates/out_of_stock.html.haml

And on the checkout pages, we redirect to the cart and display an error:

An item in your cart has become unavailable.

Code references:

• app/controllers/checkout_controller.rb
• app/controllers/concerns/order_stock_check.rb

Do we need to test this to confirm?

@mkllnk ah yes stupid me we could reuse the same message! However what we need to change is the fact that the user needs to remove the item themselves. Here we want to remove them automatically (with no action from the user). So no more redirection to cart when this happens.
