Items Awaiting Pickup Modal

User story:
As a patron who has requests awaiting pickup
I want the circ desk worker to let me know they are there when/if I come up to check something out
So I don't leave the library without picking up my items

Scenarios:

1. Scenario
   • Given User A has X items awaiting pickup for a request at Service Point P:
     • Request status = Open - Awaiting pickup (already working) OR Closed - Pickup expired (to be implemented in UIREQ-59)
     • Item Status = Awaiting pickup
     • Request pickup service point = Service Point P
   • When User A is scanned/entered into the Patron field in the Check Out app AND User A is acting on behalf of themselves (not as a proxy for someone else) AND the current service point is Service Point P
   • Then:
     • "Items awaiting pickup" modal should display with
       • Title of modal: Items awaiting pickup
       • Body of modal: Borrower has <number of items> awaiting pickup at this service point.
       • Controls:
         • Close - Button
         • X on window for closing (same as Close)

Mockups: Popup should use same styling as check in modals described in UICHKIN-49 and UICHKIN-50
