Fileupload breaks http requests interceptor cycle when imported in a standalone context

[pplaissy]

Describe the bug

Hi!

Say we have a standalone app

// an app config file which register a http interceptor
export const appConfig: ApplicationConfig = {
  providers: [
    provideHttpClient(withInterceptors([
      apiRequestsInterceptor
    ])), 
    provideAuth(authConfig)
  ]
};

// the http interceptor
export const apiRequestsInterceptor: HttpInterceptorFn = (req: HttpRequest<unknown>, next: HttpHandlerFn) => {
  console.log("intercepted");
  // here the access token is added to headers
};

// and finally a component
@Component({
  selector: 'test',
  standalone: true,
  imports: [],
  templateUrl: './test.component.html'
})
export class TestComponent {
}

Everything works fine until I import the Fileupload component.
From this import, the interceptor is ignored.

import { FileUploadModule } from 'primeng/fileupload';
@Component({
  selector: 'test',
  standalone: true,
  imports: [FileUploadModule],
  templateUrl: './test.component.html'
})
export class TestComponent {
}

It's because Fileupload imports itself HttpClientModule which is incompatible in standalone context.

I'm going to make a pull request to suggest the fix.
