smol change to the message printing - now in a one liner with the timezone too

also added a teensy 0.5s sleep after apply to allow the logs to pause whilst pushed to try to pin message to the bottom.

Sweet. I think for now the tiny message grab at the bottom is unavoidable though. Even with a forced sleep it might still capture them if the controller is a bit slow on a busy cluster.

With more staged build script, or staged build pods, we could probably handle this better in lagoon-kbd in the future though.

This is a great step towards incremental logs!
