i18n(shell): translate auth, nav, password-strength, and trend-hints into es/fr/it/pl

Localises the user-facing shell strings: auth (sign-in / sign-up,
passkey fallback, password validation), nav (sidebar labels, theme
toggle), password-strength meter, trend-hints countdown, notifications
breadcrumbs, common copy/unknownError, format.dateShort with locale
date order (dd/mm/yyyy for es/fr/it, dd.mm.yyyy for pl), and the
errorBoundary fallback title. Placeholders {minLength}, {count} all
preserved.
