Fleet version: 4.66

💥  Actual behavior

While switching our labels over to gitops, I encountered an error message when the Apply latest action was run and attempting to delete a static label with hosts assigned to it.

Error: DELETE /api/latest/fleet/labels/Santa%20test%20device received status 422 Validation Failed: the operation violates a foreign key constraint on labels: Santa test device

🧑‍💻  Steps to reproduce

1. Create a static label in the UI and assign hosts to it
2. Deploy labels via GitOps, making sure not to include the label you created in the UI so it will delete it
3. Observe behavior

🕯️ More info (optional)

I had to manually delete the label in question from the UI in order for my GitOps run to succeed.
