Show most recent sender in inbox, not thread starter

Problem
The inbox currently displays the person who started a conversation thread, even when recent messages are from different senders. This makes it difficult to quickly assess message priority or route to the right teammate, especially when the original sender is no longer relevant or has left the company.

Request
Update the inbox list view to show the most recent sender in each conversation, not the original thread creator, so users can better prioritize and route messages.
