Subject: [PATCH] feat(admin): add lead author columns to articles and letters

Introduced custom columns in the admin list view for both articles and letters to display the lead author. This enhancement improves clarity by directly showing the lead author and removes the default author column. The new columns are populated based on post metadata.
