Stack switch member details in Device data table for Cisco and Juniper

The Device data table does not currently populate stack switch member details for Cisco and Juniper devices when exporting map data, leaving stacked chassis information incomplete in the exported table. This enhancement would extend data collection to capture stack member details for Cisco and Juniper devices, using the relevant device commands that expose stack membership, and populate that information in the Device data table. Customers relying on exported data tables for documentation and troubleshooting would gain accurate, complete visibility into stacked switch configurations without needing to manually supplement the exported data.
