fix(i18n): translate the device-notification namespace for es/fr/it/pl

The entire insights.rhythmEvents namespace — section title, intro, the
load-error, and the medical-adjacent device-detection disclaimer — shipped
the English string verbatim in es/fr/it/pl. The locale-integrity guard only
checks key shape + placeholders, so the copy-paste passed CI while rendering
English on a Spanish/French/Italian/Polish device-notifications card,
disclaimer included. Translate the four keys into real localised copy.
