Approving the small dashboard change:

/approve

Also, manually forcing approval for the small kedge, proxy and service-waiter because they all seem safe, super small, and the PR is apready LGTM'd + approved by multiple people. Let's not overdo this approval thing. 😅

EDIT: Ah, didn't need to manually force these approvals for some reason. Great!
