fix: Remove cart.js from erpnext-web bundle

- Due to it being in the bundle, controls bundle was required for Dialogs used in cart
- But this is exclusively used in `cart.html`
- It has no reason to load and break the login page
- Moved it back to where the html is, it is now back to being tightly coupled with its html

erpnext/public/js/erpnext-web.bundle.js
