Data import settings page's 4th pane for Match Profiles: Header action for Duplicate

Purpose: To define the actions of the Data import settings Mach profile 4th pane Header Actions. This story adds the Duplicate functionality. Delete functionality is covered in UIDATIMP-215. Edit functionality is covered in UIDATIMP-143 and UIDATIMP-182

As a staff person
I want to be able to duplicate individual match profiles via the 4th pane header
So that I can more easily create similar match profiles without starting from scratch every time

NOTE: 4th pane header showing the caret next to the Match profile name and the edit pencil was created in UIDATIMP-140

Scenarios

1. Scenario 1
   • Given the Data Import Settings/Match profile 4th pane, showing the details of an individual match profile
   • When a User clicks the down caret next to the name of the Match profile in the header
   • They should see three options in the caret menu (see 42a-Settings Match profile detail caret options.png)
     • Edit, preceded by the pencil icon
     • Duplicate, preceded by the duplicate (2 boxes) icon
     • Delete, preceded by the trashcan icon (even though the mockup doesn't show the trash can)
2. Scenario 2
   • Given the action caret in the header of the Data Import Settings/Match profile 4th pane
   • When the user clicks the "Duplicate" option
   • The New match profile screen should open and cover the full screen (as detailed in UIDATIMP-138), except
     • Populate all fields with the data from the match profile that is being duplicated
     • And ensure the new match profile is not connected to any job profiles
3. Scenario 3
   • Given the duplicated match profile
   • When the user clicks the "Save" button
   • Then if the match profile name is unique, the match profile should be saved
   • And appear in the list of match profiles, sorted into the list appropriately
4. Scenario 4
   • When the user clicks the "Save" button
   • Then if the match profile name is not unique, display a red exception toast: New profile not created: Match profile [match profile name] already exists similar to the attached File Extension Already Exists.PNG
   • And keep the user on the editing screen for the duplicate profile
5. Scenario 5
   • Ensure automated testing coverage for this new code is 80% plus and confirm with screenshot
