refactor(plugins): update JPush config and improve SmartImage loading

- Update `withJPush` plugin to support Expo SDK 56+ by using `JPUSHService.setup` instead of `JCoreModule.setup` and adding `UNUserNotificationCenterDelegate` conformance.
- Improve `SmartImage` component by adding a ref to prevent loading state flickering when transitioning from preview to original image.
- Upgrade `@shopify/flash-list` dependency.
- Add transition prop to `SmartImage` for smoother image loading.
