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
Refactor LocalDataSource to reuse the shared database connection from database.ts, avoiding OPFS file handle conflicts. Add retry logic with exponential backoff for database open operations, particularly important for Web/OPFS environments. Also add dynamic theme support to chat input and message bubble styles, using theme colors instead of hardcoded values for better light/dark mode support.
BREAKING CHANGE: Database initialization now requires userId to be passed explicitly for user-specific databases
- Updated RegisterScreen to support a multi-step registration flow with components for email input, verification, and profile setup.
- Added new components: VerificationCodeInput, StepIndicator, and corresponding types for step management.
- Enhanced background service to check authentication status before executing tasks, improving app reliability.
- Updated TypeScript configuration to include module resolution and JSON module support.
This update significantly improves the user registration experience and ensures background tasks are only executed for authenticated users.
