Implement Author Description on Merge Page

Closes #9429

Description

This PR introduces the display of author descriptions on the merge page. The author descriptions will provide more context about each author during the merge process, improving the usability and user experience and helping librarians disambiguate authors, and avoid accidentally merging authors that shouldn't be merged.

Changes

1. Conditional Display of Author Description:

   • Added logic to conditionally display the author description if it exists. If no description is available, a placeholder message "No description." will be shown.
   • Used the TruncateString macro to limit the displayed author description to 250 characters for better readability and to ensure a consistent layout.

2. Updated Template:

   • Modified the HTML template to include the new logic for displaying author descriptions.
   • Maintained the existing template structure and ensured compatibility with the current styling and layout.

How to Test

1. Run the Application:
   Ensure the application is running locally.

2. Navigate to the Merge Page:
   Go to the merge page where authors are listed for merging.

3. Verify Author Descriptions:

   • Check that authors with descriptions have their descriptions displayed, truncated to 250 characters.
   • Verify that authors without descriptions show the placeholder text "No description."

4. Check for Errors:
   Ensure there are no errors or layout issues introduced by these changes.
