[Improve Post Comment Section] Show the Last 3–5 Comments on Feedback Posts

Users currently only see the most recent comment on a feedback post, which makes it easy to miss ongoing discussions.

They often don’t realize there are multiple comments unless they click “See whole discussion.”

To improve visibility and match expectations set by tools like Canny, show the latest 3–5 comments directly in the post preview, with the full thread loading on demand.

This would make discussions more discoverable and improve the overall feedback experience.
