UAT - Corrections: Previous director name not shown on pdf output

### Problem Statement
The PDF generated after a Director name correction omits the previous director name.

The legacy COLIN system displays both the previous and updated director names.

### Current Behavior
When a staff correction updates a Director’s name, the resulting PDF only shows the new name. The prior name is not visible anywhere in the document.
### Expected Behavior
The PDF should display the director’s previous name alongside the updated name, aligned with COLIN output and historical correction practices.
### Business Requirements
- The system records both previous and updated Director names for director correction filings.
- The generated PDF presents both names in a clear, readable format.

### Business Impact
Staff reviewing historical filings lack full visibility of what specifically changed. External users relying on PDFs for legal or audit purposes do not receive a complete correction record.
