(W5) Monica and Mike (Add mark for item already on list)

9. As a user, I want to mark an item already on my shopping list as purchased #31

AC:

• User is able to tap a checkbox or similar UI element to mark an item in the list as purchased
• Item should be shown as checked for 24 hours after the purchase is made (i.e. we assume the user does not need to buy the item again for at least 1 day)
