Integrate 'Stop' and 'Start in Safe Mode' options in Studio UI for Clusters and Instances

Enhance the Studio UI to include new options for managing clusters and instances:

1\. Add a 'Stop' option to the cluster card drop-down menu, alongside the existing 'Terminate' option.
2\. Include a 'Stop' option in the admin drop-down on the instances table page, applicable to instances within a fabric cluster.
3\. Provide 'Start' and 'Start in Safe Mode' options for stopped clusters or instances.
4\. Ensure Fabric Connect can connect to stopped instances, with access to logs and configuration via existing tabs, while disabling other tabs.
5\. Handle the 'harper admin' role to allow viewing and accessing all organizations without explicit addition.

This task involves UI changes and possibly backend adjustments to support these functionalities.
