Management of Corrections💡

I would like to propose a feature to improve management of corrections, which would allow to mark workflow items that need to be corrected, and then through a toggle button in the UI, display or hide the corrected steps. The end user would then have the possibility to see the final or "clean" process, or has the view of all detailed steps including those that were corrected.

The implementation could be as follows

1. Introduce a label "correction" (or similar) that can be applied to a workflow item
2. Add a toggle button in the frontend to display or hide corrections
3. Add a specific permission to "mark as correction" that can be given to the users - this would add a level of control to the feature.

Toggle button to display and hide corrections and implementation of its functionality can be done in a separate pull request. Displaying or collapsing corrections should be purely presentational functionality.

List of required changes: (subject to change)

• New action button visible to users that have right to correct wf items
• Clicking "correct" button opens a Correction dialog similar to Edit workflow item
• Submitting correction should leave original wf item unchanged. Instead, new correctional WF item is created, linked to the corrigendum by its ID. (Who should be the assignee?)
  Numerical changes can be calculated from differences between an original and a correction, and these should be written in a new workflow item.
• reducer actions + reducers
• translation keys
• E2E tests

If only select users have the right to issue corrections, additionally:

• correction API endpoint (/api/workflowitem.correct) ?
• correction permissions
• E2E tests
• Update provisioning data

For now, simple solution of enabling input of negative values (#1407) in workflow is implemented.
