Increase button size and simplify step text

Updated `RadzenButton` components in `Home.razor` to use `Size="ButtonSize.Large"` for improved visibility and usability.

Simplified the step description in `Response.razor` by changing the `RadzenText` text from "Step #1: Choose or Create a Template" to "Step #1: Choose a Template," reflecting a streamlined process.
