add:enhance comments list with scroll, limit, and styling

- Add maxComments, showCommentForm and isScrollable props to
CommentsList
to limit displayed comments, toggle the form, and enable a scrollable
comments container. Show a "+N more comments" indicator when limited.
- Adjust CommentForm and list styles (padding, background, flex
behavior, responsive heights). Pass currentUserId and new props from
FindPreview and FindCard where applicable.
