chore: Reload conversation data in ActionCableBroadcastJob before sending (#10876)

During high-traffic periods, events may appear out of order, causing the
conversation job to queue outdated data, which can lead to issues in the
UI. This update ensures that only the latest available data is sent to the UI.

The conversation object is refreshed before sending it to the UI.
