Add TalkReply class and tests.feature/talk-reply

- Add struct TalkNotificationData to handle token and messageId.
- Handle chat and call notifications with the new struct.
- Add talk token and messageId to data roles in ActivityListModel.
- Add Talk Reply component to the ActivityList.
- User Loader to display the TalkReply component.
- Move Talk Reply from ActivityItem to ActivityItemContent due to PR #4186.
- Use TextField instead of Text.
- Disable send reply button instead of changing border color when field is empty.
