feat: Implement pull-to-refresh functionality across various components

- Added `PullToRefresh` component to enable pull-to-refresh behavior in `StopList` and `Estimates` pages.
- Integrated `usePullToRefresh` hook to manage pull-to-refresh state and actions.
- Created `UpdateNotification` component to inform users of available updates from the service worker.
- Enhanced service worker management with `ServiceWorkerManager` class for better update handling and caching strategies.
- Updated CSS styles for new components and improved layout for better user experience.
- Refactored API caching logic in service worker to handle multiple endpoints and dynamic cache expiration.
- Added auto-refresh functionality for estimates data to keep information up-to-date.
