Bag should have an infinite scroll powering it

This isn't a priority, but is something to thing about later on.

The issue mentions adding infinite scroll to 'Bag', likely a UI component for a grocery shopping app. First, locate the frontend code for the bag view, possibly in a React component. Understand how items are currently fetched and displayed. Research existing infinite scroll libraries or implement a custom solution. Determine what 'done' looks like by checking if the UI loads more items as the user scrolls without breaking existing functionality.
