fix(i18n): restore relative-time plural keys swept by W12 tighten

W4's pluralised relativeMinutesAgoOne/Other + relativeHoursAgoOne/Other + relativeDaysAgoOne/Other keys were silently removed across all 6 locales when W12's i18n tighten (commit 2390438e) re-applied the legacy singular keys. The formatRelativeTime helper still reads the *One/*Other keys, so the Insights hero, Daily Briefing, and Coach history rail all paint raw key strings to users.

v1.4.43 W10 critical-reconcile — code-reviewer C-1, design C-1, simplifier C-1.
