Prior to this change the InformationFetcher would create a new
instance of a SystemInformation object while the Monitor UI
would display the last SystemInformation object. If any of the
tasks to create the new SystemInformation object failed, then
the Monitor would continue to display the old information.

With this change the new SystemInformation object is always
used, and if it's incomplete then a new message is shown on
the Messages page.

This change also includes a new computeMessages method that
is called from SystemInformation.finish. This method includes
new messages that use new priorities and categories.

Finally, this change introduces a new Tablet Recoveries page
in the Activity menu. Information for this page is gathered
from metrics emitted by the server processes and information
in the tablet metadata.

Closes #6306, #6106

@dlmarion dlmarion added this to the 4.0.0 milestone May 1, 2026

+ " exists, but no resources assigned. Consider removing the resource group");
