Wire the existing useLoadMore + useMessagesHasMore pagination hooks into the
Messages view: add a "↑ Load older messages" button at the top of the list and
auto-load the next (older) page when the user scrolls to the top. Backend
messages.list already returns a created_at-based nextCursor (DESC order), so
older pages are just subsequent cursors. Newest-first live feed is preserved;
the load-older control is hidden during search.
