Is your feature request related to a problem? Please describe.
I want to be able to add custom elements at the end of each AI response in RadzenAIChat. Currently, there is no way to define a footer template for responses.

Describe the solution you'd like

Introduce a ResponseFooterTemplate property or similar.
This template would allow appending custom Blazor components or buttons to each response.
Example: action buttons like 👍 / 👎, Download, or other developer-defined actions.
Elements should be fully interactive and trigger Blazor events or callbacks.

Describe alternatives you've considered

Wrapping the chat component and manually appending UI elements, which is cumbersome and not integrated.

Additional context

Goal: make each AI response interactive with custom UI elements without modifying the core chat component.

<RadzenAIChat @ref="chat"
              Messages="@messages">
    <ResponseFooterTemplate Context="message">
        <button class="btn btn-sm btn-primary" @onclick="() => OnThumbsUp(message)">👍</button>
        <button class="btn btn-sm btn-secondary ml-2" @onclick="() => OnDownload(message)">Download</button>
    </ResponseFooterTemplate>
</RadzenAIChat>

I've just pushed MessageTemplate that can be used to declare whatever UI you need: 8eeda0e647
