SECURITY: add pagination to post replies
When a post has some replies, and the user click on the button to show them, we would load ALL the replies. This could lead to DoS if there were a very large number of replies.

This adds support for pagination to these post replies.

Internal ref t/129773

FIX: Duplicated parent posts

DEV: Query refactor
