The customer mail of health_degraded / health_critical / health_recovered no longer
appends the raw details JSON (frozen wire text, English or Hungarian whatever the
household's language). It says where to read the details: the dashboard. The
operator mail keeps the note; every other event keeps its note.
Red tests: r79_health_mail_test.go (2 failed on the old templates.go). Goldens
regenerated for the six health mails.
