Bohan Jiang a9e82c7973 MUL-7282: fix(comments): delete only the selected comment and keep its replies (#8323) ...

Deleting a comment removed every reply under it, through the parent_id ON DELETE CASCADE. Now delete removes only that comment: one with replies becomes a tombstone (deleted_at set, body/attachments/reactions/resolution cleared) so the replies keep their parent, and one without replies is removed along with any tombstone ancestor left empty.

Tombstones are read-only and are never agent input. Every write to a comment's children takes its owners first (issue -> comment -> child), and a comment commits together with the attachments it was posted with. Clients only promise that replies are kept when the server declares comment_delete_keep_replies_supported, and then delete through DELETE /api/comments/{id}/keep-replies, which older servers do not route.
