fix: Default hasMoreResults to true while loading

The infinite scroll trigger was broken because hasMoreResults returned
undefined (falsy) when SWR data hadn't loaded yet. This prevented the
InfiniteScroll component from triggering the next fetch.

Now hasMoreResults defaults to true while isFetchingClimbs is true
(so infinite scroll works during SSR hydration), and false after loading
completes with no data.
