Refactor ServerSideSessionCleanupHost to inherit from BackgroundService instead of directly implementing IHostedService. This fixes an issue where StopAsync throws when called multiple times without a corresponding StartAsync call, which occurs in WebApplicationFactory testing scenarios. Fixes: DuendeSoftware/issues#1196
Use while (!stoppingToken.IsCancellationRequested) instead of while (true) with manual cancellation checks, removing redundant code.
