Process status notifications should use the process name when it is set

When the state of a process changes and the user is monitoring it in the process details view, the change can cause a desktop notification (not a frontend notification) to appear if the user gave permission for them. The notifications are titled {process.mode} process {process.id}, for example Workers process ba7c285d-728c-4ab1-92d5-584955a67080. They could instead use the process name when it was set, for example Training process "my cool model", which would make monitoring multiple processes a little nicer.
