feat(ui): replace custom pull-to-refresh with use-pull-to-refresh library for simplicity

- Remove custom usePullToRefresh hook and PullToRefreshIndicator
- Add use-pull-to-refresh library dependency
- Create simple RefreshIndicator component
- Apply pull-to-refresh to Explore and Me screens
- Simplify implementation while maintaining functionality
