i18n(relative-time): branch on count === 1 to render singular forms

formatRelativeTime always read the *Ago key with count=1, so a German user reading the Insights hero saw 'vor 1 Minuten' / 'vor 1 Stunden'. Splits each bucket into One / Other variants across all locales and branches on count === 1 in the helper, matching the dashboard.staleHintWeeksOne / Other pattern already in the bundle.
