Add preview action to choose jobs screen

Purpose: To be able to run uploaded files in preview mode

NOTE: Keep Blocked and hide the preview button until backend preview fxn is completed

As a staff person
I want to be able to run an imported file in Preview mode
So that I can review the results and then run it for real before all the changes are committed in all of the apps.

See attached wireframe Apply a job profile to the uploaded files.png

Scenarios

1. Scenario 1
   • Given the 3rd pane (job profile details) of the Data Import "choose jobs" screen
   • When a user clicks the down caret next to the name of the Job profile
   • Then add an option to the existing ones:
     • Run (already exists)
     • Preview
     • Edit job profile
2. Scenario 2
   • Given the Preview option in the Job profile caret
   • When a user selects the Preview option
   • Then display a modal similar to the attached Save changes modal.png
     • Header: Are you sure you want to preview this job?
     • Text: You have selected the [job profile name] job profile to Preview the uploaded files
     • Buttons:
       • on left: Cancel [default]
       • on right: Preview
3. Scenario 3
   • Given the Preview modal
   • When the user selects Cancel
   • Then return them to the "choose jobs" page and allow them to assign a different job or select a different option
4. Scenario 4
   • Given the Preview modal
   • When the user selects Preview
   • Then begin the import in Preview mode
5. Scenario 5
   • Ensure automated testing coverage for this new code is 80% plus and confirm with screenshot

Note: we will eventually have different permissions for users who can Preview files versus users who can Run files. Please ensure this will be possible with the design.
