integrated verify cart page, and did the warning labels

[CrazEpic]

Verify cart page now calls the backend instead of being hardcoded. Also warning checks are created. For the category rule, I interpret it as 1 unique item / category.

edit: 1 item / category after deals now

Shown are various carts. There is a 3-for-1 bagel deal.

I used Postman to call backend APIs. Ping me if you need them.

i'm seeing a warning for over category limit, despite the two items being in separate categories see my inline comment on utils/cartCalculations for the above issue

I think there should be a mechanism to cull carts stale carts (one which are past when they would reasonably still be relevant) the above image is what i'm thinking about for the search, although we could also have some api that is run at some interval to remove carts older than a cut off.

i know this is just the verify side, but i think we should make an issue for updating the cart date on submission for verification. so that we can track when a cart was submitted, displaying carts based on that date.

i would hide the count when no cart is selected

I'll make a separate issue for the old cart clearing
