[ENH] - An admin stopping a server created by another user does not work (on Nebari)

[Adam-D-Lewis]

Feature description

Not sure if this is specific to Nebari, but when an admin user tries to stop a server created by another user in the UI, the UI shows server stopped successfully, but the logs show an error occurred. Logs are below. In this case my user tried to stop a lumenai server created by someone else.

Value and/or benefit

bug fix

Anything else?

Servers are able to be stopped successfully by going to jupyterhub's admin panel and stopping them there.

I believe this is disabled for now, as in stopped servers can be started by people having access to the shared server but not other way around, but yes the UI could better reflect on what happened.
