Translations and CHANGELOG for the redesign, the agent's link and Scheduled

51 sentences of the app's own in all eight languages (gen-i18n.py OWN), the rest from the
server's catalogues; 11 sentences no page uses any more are gone. The title bar's pills stay
inside its height at touch sizes; a failed scheduled run has its own notification words.
