refactor: improve feed loading and infinite scroll reliability

- Add debouncing and loading state to InfiniteScroll component to prevent duplicate entries
- Refactor updateAllFeed into smaller, focused functions for better maintainability
- Add proper error handling and type assertions
- Optimize test performance with networkidle waits and better selectors
- Fix strict mode violations in Playwright tests
- Clean up test configuration by commenting out unused browser targets
