build(config): update bundle identifier and add signing plugin

feat(notification): improve JPush integration and message sync reliability

- Update iOS bundle identifier to `cn.qczlit.weiyou`
- Add `withSigning` Expo plugin
- Enhance `withJPush` plugin with improved Swift AppDelegate injection logic
- Update JPush default channel to `developer-default`
- Optimize `MessageSyncService` to prevent race conditions in unread count updates
- Implement promise deduplication for `fetchUnreadCount` to prevent redundant network requests
- Add `setConversationsWithUnread` to `useMessageStore` for atomic state updates of conversations and unread counts
