RefreshReferenceMessageHandler

Refresh referenced (quoted) message callback.

When a message contains a reference to another message, this handler refreshes the referenced message content. The refresh operates in two stages:

1. onLocalMessages - Callback with results for messages found locally

2. onRemoteMessages - Callback with results for messages fetched from the server

If all messages exist locally, only onLocalMessages is called. If some messages are not found locally, onRemoteMessages is called additionally.
