feat(notification): migrate from expo-notifications to JPush push service

Replace expo-notifications with JPush for push notifications across the app.
This includes adding JPush native module dependencies, configuring the JPush
plugin in app.json, implementing jpushService wrapper, and updating notification
services to use JPush APIs. Also adds device registration on token refresh for
both mobile and web platforms.

BREAKING CHANGE: expo-notifications removed in favor of JPush for push notifications
