- Recent Activity rendered literal {{email}} — the per-row t() call didn't
pass the email interpolation var. Source it like formatActivityMessage
(metadata.email ?? actorName).
- Customer 'Deine Galerien' dates rendered en-US ('May','Jun') under a German
UI because they used raw date-fns format(parseISO(iso),'PP') with no locale.
Route through useLocalizedDate().format → honours general_date_format + the
active language.
