Update dependencies and refactor authentication logic in App component

- Upgraded @powersync/react to version 1.7.0 and @powersync/web to version 1.25.1 in package.json and package-lock.json.
- Updated @powersync/common dependency to version 1.36.0.
- Refactored authentication logic in App component to use useEffect for fetching user ID from Supabase on component mount, simplifying the code by removing unnecessary state management for authentication status.
- Adjusted SupabaseConnector to streamline the anonymous sign-in process.
