Support Monthly Time Range in Scheduled QApp Settings

NetBrain currently limits the time range configurable in scheduled QApp settings to 1440 minutes (24 hours), which prevents customers from defining a monthly scheduling window directly within the QApp settings interface. This enhancement would extend the available time range option to support up to 24*30 hours, allowing a monthly benchmark schedule to be configured natively. Supporting this broader range would remove the need for manual workarounds and give customers greater flexibility when planning longer-interval automated QApp executions.
