Empty serviceName in fleet StatefulSet

[torchiaf]

Setup

• Rancher version: v2.9-a6bb9619c947a9c79ad420660e05cb10b02bf515-head
• Installation option (Docker install/Helm Chart): Helm v2.16.8-rancher2
• Kubernetes version: v1.26.4 +k3s1
• Cluster Type (Local/Downstream): local and downstream RKE2

Describe the bug

serviceName in cattle-fleet-local-system/fleet-agent StatefulSet is empty string.
This is blocking the redeploying/scaling operations in the UI.

We should verify if the field is missing for a backend issue or we need to fix the validation UI side.

To Reproduce

• Go to local or downstream cluster explorer
• Go to Workspace -> StatefulSet -> fleet-agent
• Click on side menu -> click on Redeploy / Scale buttons

Result
The UI shows a validation error, 'Service name is required'. The error is also visible in the console.

Screenshots

Additional context

It's still possible to restart the agent using the CLI

kubectl rollout restart statefulset fleet-agent -n cattle-fleet-local-system

This may have to be back ported to 2.9.x but if our capacity for 2.9.0 has room, we can put this back in.
