Refactor Cases Consolidate section in DataVerification screen

[governmentSponsored]

Within our DataVerification screen, under consolidations, staff assignments for the Cases To Consolidate can take a long time to come back. We are doing individual calls to get assignments for each individual case, which is slow. We had a similar problem in the StaffAssignment screen, we solved this issue by getting cases by an array of caseIds and mapping those back in a single call.

h3.##Pre-Conditions:
Functioning data verification screen with consolidations

h3.##Acceptance Criteria:

• The Cases to Consolidate section on the DataVerificationScreen uses functionality similar to that of the StaffAssignmentScreen when getting case assignments for those cases
• The order comes back with the staff assignments in one call rather than separate calls for each

h3.##Pain Avoided/Frustration Saved:

• Assigned Staff will come back faster for the user

h3.##Breadth/Pervasiveness of Problem:

• Staff assignment can take a bit to come back, especially on consolidation orders with many cases involved
• Consistency in data calls

h3.##Complexity of Problem (Low, Medium, High) and Why it's Complex:
Complexity is: Low-medium
