Enable editors to redact author names when included in revision request responses

Is your feature request related to a problem? Please describe.

User Story: I am an editor on a journal with an anonymous review process. Sometimes authors add their names to their response letter to reviewers. I need to remove these before the reviewer sees them. Currently there is no functionality to edit this, other than through the admin.

Describe the solution you'd like

• A page which allows editors to safely redact text submitted by authors so that anonymity can be preserved.
• Validation and warning when authors submit text, especially in 'letter' form which naturally would include a name, that pattern-matches for the author(s) names, but allows a user to 'submit anyway' in case of false positives.

Additional context
Add any other context or screenshots about the feature request here.

This is the result currently only possible through editing in the admin interface.

Start by reviewing the existing admin-interface workflow for editing revision request responses and identify where editors currently encounter the submitted text. Then map the editor-facing response workflow and its anonymity requirements. Done means editors can redact author names safely, with validation and a submit-anyway option for false positives.
