A seasonal currency with no purse.seasonal.currency.<type> text rendered the raw key (e.g. 'purse.seasonal.currency.11') in the purse. Share PurseView's existing localizeWithFallback helper (extracted to api/utils with a pure resolveLocalized core + tests) and use it in SeasonalView with an empty fallback, so an unnamed currency shows just its icon + amount. Verified in-app.
