feat: refine notification title handling based on message type

- Enhanced CustomPushNotification to dynamically set notification titles for groups, direct messages, and omnichannel based on the Ejson payload.
- Updated Ejson class to include a room name field for better context in notifications.
- Improved iOS NotificationService to determine notification titles based on payload type, ensuring accurate representation of sender or room names.
