I came across a bug that I will try to recreate where the order of keys were confusing, and the new key got added to the top of the list.

Right now, the keys are returned in ascending creation order.
So from oldest to newest.
(Previously, there was no ordering)

If I recall the labels are not unique. It's not technically possible for someone through the UI to add two keys at the same time. So I think it makes sense to provide a bit extra metadata. Could also be useful for us to understand when people get to the point of adding more keys.

Didn't fully understand this point...

We already have a createdAt field in the keys table btw.
It's just that we are not showing it in the UI.
