Prevent SwipeRefreshLayout from intercepting while list can still scroll up

This PR fixes an issue where pull-to-refresh could trigger while the files list
was not at the top, causing an unexpected refresh and interrupting scrolling.

Implementation:
- Set a ChildScrollUpCallback on SwipeRefreshLayout to return true when the
  RecyclerView can still scroll up (canScrollVertically(-1) == true). This
  prevents SwipeRefreshLayout from intercepting gestures mid-list.
