fix: add missing balance cache invalidation after mutations

- Subscription.tsx: devicePurchase + trafficPurchase onSuccess → invalidate ['balance']
- RenewSubscription.tsx: renewMutation onSuccess → invalidate ['balance']
- SubscriptionPurchase.tsx: purchaseMutation onSuccess → invalidate ['balance'] + ['subscriptions-list']
- subscription.ts: refreshTraffic uses withSubId (already fixed, formatting)
