🥕[Bug]: `runtime` defaults start but do not run.

If you use all defaults in your configuration, like this:

## Configuration snippet

```json
"runtime": {
"mode": "development"
},
```

And then you `dab start` it runs!

However, when you navigate to the endpoint, you get:

```
info: Microsoft.AspNetCore.Hosting.Diagnostics[1]
Request starting HTTP/1.1 GET http://localhost:5000/ - - -

## Problem

```
No authentication handler is registered for the scheme 'OAuthAuthentication'. The registered schemes are: StaticWebAppsAuthentication. Did you forget to call AddAuthentication().Add[SomeAuthHandler]("OAuthAuthentication",...)?
```

Something changed to make this required.

## Also

```
Did you forget to call AddAuthentication().Add[SomeAuthHandler]("OAuthAuthentication",...)?
```

This is an internal message and should NOT be exposed.

Inizia da src/Core/AuthenticationHelpers/ClientRoleHeaderAuthenticationMiddleware.cs alla riga 76 e da src/Service/Startup.cs alla riga 374, usando la configurazione di runtime predefinita segnalata per riprodurre il problema della richiesta. Traccia il motivo per cui viene selezionato lo schema OAuthAuthentication quando è registrato solo StaticWebAppsAuthentication. Il lavoro è completato quando la configurazione predefinita serve correttamente l’endpoint e il messaggio interno del gestore di autenticazione non viene esposto.
