Display the "type" of event log on overview page

The overview page before displayed the "Severity" of the event log
in the name field. It now displays the type. Type is from the
"Message" field in the event log. An example of the type is:
"xyz.openbmc_project.Software.Version.Error.ManifestFileFailure".
This is much more useful than the "Severity" ( e.g.
"xyz.openbmc_project.Logging.Entry.Level.Error"). Severity is
still displayed in the event log, above the type.
A similar change for the "event logs" page was made here:
https://gerrit.openbmc-project.xyz/#/c/8916
