Create a sample on how to use NServiceBus in a Blazor app

[lailabougria]

As requested by one of our champs:

Blazor server has full access to all the things server-side. It would be a cool sample so see:

• a button that triggers an NServiceBus message
• the result of that handler/saga being routed back via messaging to that user (or /and other users)
• see the UI update that "your task has completed [link]"
