differences between `remote` actions/sequences and `local` app:dev

## Listing Web and Non-web urls

`Remote`:
- **web**: will show the cdn host
- **non-web**: this shows the `package/action` path for the sequence that is created when an action has `require-adobe-auth:true`
- **non-web**: will always use the adobeioruntime.net host, not the adobeio-static.net cdn host

`Local`:
- **web**: will always show localhost
- **non-web**: this **does not** show the `package/action` path for the sequence that is created when an action has `require-adobe-auth:true`
- **non-web**: since we don't have a cdn for localhost (no point), the host is the same for both web and non-web

## Calling a non-web action/sequence

`Remote`:
- adobeio-static.net cdn: will always return 404
- adobeioruntime.net: will always return 401

`Local`:
- will always return 401

## Calling a web action/sequence: error response object

`Remote`:
- will have both `code` and `error` properties, e.g.
```
{
"code": "7HlbgAP51Dxwagx2jIZYxS4g9a1ZJeW3",
"error": "Response is not valid 'message/http'.",
}
```

`Local`:
- will only have the `error` property, e.g.
```
{
"error": "Response is not valid 'message/http'.",
}
```

Comienza por la implementación de app:dev y reproduce los casos remotos y locales enumerados para el listado de URL, las llamadas que no son web y las respuestas de error de las acciones web. El issue no especifica archivos, tests ni un comportamiento deseado, por lo que primero debe aclararse el resultado previsto antes de poder evaluar si se ha completado.
