Pull Request Overview

This PR fixes Server Side Rendering (SSR) compatibility for the Dot Pager component by addressing two SSR-related issues: adding a check for the document object in the swipeable component and replacing the deprecated use-subscription module with React's native useSyncExternalStore hook in the RTL functionality.

Key changes:

• Migrated from use-subscription to useSyncExternalStore in the RTL hook for better SSR support
• Added a document undefined check in the swipeable component to prevent SSR errors
