Review `ChatHttpResponse`

[pmarsh-scottlogic]

When we access the API, by POST /openai/chat, we return an object that looks like this

interface ChatHttpResponse {
    reply: string;
    defenceReport: DefenceReport;
    transformedMessage?: TransformedChatMessage;
    wonLevel: boolean;
    isError: boolean;
    openAIErrorMessage: string | null;
    sentEmails: EmailInfo[];
    transformedMessageInfo?: string;
}

After #873 we add wonLevelMessage as well.

What's the problem? Well all of the following properties represent something that might be added to the chat history: reply, transformedMessage, wonLevelMessage, openAIErrorMessage, transformedMessageInfo , or at least displayed on the frontend's chatHistory. We should think about perhaps just returning a list of ChatMessages

This will require some investigation (about when, where and how the above messages get added to the font/backend chats), and a bit of poking around on both the front and back end, and then probably lots of test changes.
