When a node has an error/warning/panic that exactly matches one of its input nodes, hide the message until the node is interacted with, showing an icon. https://github.com/enso-org/enso/assets/1047859/4b1b5e3d-c236-40d7-a3e7-e6ab8182ecd5 # Important Notes - New icon is used for panics. - Opening circular menu now shifts any message out of the way, not just warnings.
