mesh-provisioner-client's report now carries failing-since (mesh-catalog 3aae6c08), kept while a module
stays failed however its words change. S21 measures a failed placing from it, falling back to the
report's time from an older client; the hysteresis of 6ffcea4f (an open condition stays while any
failure stands) is kept. This is the thorough fix that commit named.
