After adding a transaction to the cart, the transaction does not appear on the `CartOverview` list

Blocked until: https://github.com/Textualize/textual/issues/3036

After adding some logging on the F2 Add to cart, CartOverview.on_mount method and CartOverview.____sync_cart_items method we can observe:

We can observe:

178  2023-07-31 13:23:00.342 | 🐞 DEBUG    | clive.__private.ui.operations.cart_based_screen.cart_overview:on_mount:76 - Watching 139843438964992 of 139843438967392
287 2023-07-31 13:23:05.783 | 🐞 DEBUG    | clive.__private.ui.operations.operation_base_screen:__add_to_cart:113 - Updating reactive 139843438964992 of 139843438967392

So we can see only 2 logs and not 3, because there is a missing log of the CartOverview.____sync_cart_items method. Textual doesn't call this method when reactively updating profile_data when it should.

That's because this method was changed to be an async method in recent changes and textual seems to have an issue with self.mount on async methods
