fix: improve Toast visibility and allow tariff deletion with subscriptions

- Toast: use solid bg-dark-800 background instead of transparent gradient
- Toast: increase border opacity for better visibility
- Tariffs: allow deletion even with active subscriptions (shows warning)
- Add confirmDeleteWithSubscriptions translation to all locales
