Description

• !43955
• It fixes the Change analysis (Impacts, Control list) and plan (Deployment plan, Backup plan, Checklist) fields rendering as raw HTML instead of formatted content in the exported PDF.
• The content fields were incorrectly passed as part of the label argument via sprintf(), preventing the PDF renderer from processing them as HTML. Each field is now passed as a dedicated content argument to displayText().
