Import log summary: Add a new status for jobs that are manually stopped by a user

Purpose: To make it possible to identify import jobs that have been manually stopped by users (versus ones that Completed with errors or Failed)

As a staff person working with Data Import
I want to be able to identify import jobs that were stopped by a user
So that I can have different expectations of what may have happened in the system

NOTE: Right now, manually stopped jobs may have some records created or updated. We will try to display as much info as possible for those records, but a full solution will need to wait for UXPROD-1383

Scenarios

1. Scenario 1
   • Given the Data Import summary for a job (on the Data import landing page or the View all page)
   • When a job is manually stopped by a user
   • Then display the term Cancelled in the Status column (instead of Completed, Completed with errors, or Failed)
2. Scenario 2
   • Ensure this story passes Accessibility testing
3. Scenario 3
   • Ensure automated testing coverage for this new code is 80% plus and confirm with screenshot

KS: Also make sure that corresponding Snapshot entity is updated with ERROR status to not break the generation calculation logic

Confirm: If User A starts an import job and User B cancels it, which user ID shows in the log summary? abreaux to check with SMEs on which they prefer
