Merge branch 'dev' into feat/supervision-des-capteurs

Le schéma backend dit que since est l'horodatage de la dernière lecture du
site, identique pour tous ses capteurs en panne et sans rapport avec le début
de la panne. Le template annonçait « depuis <date> », ce que l'exploitant lit
comme une date de début de panne.

Un site sans aucune lecture renvoie ses cinq capteurs en échec avec since à
null : le template affichait « depuis » suivi d'une chaîne vide. Ce cas dit
maintenant « aucune lecture reçue ».

Format de date explicite plutôt que 'short' : aucune locale n'est enregistrée
dans app.config.ts, donc 'short' rendait la date au format en-US.
