fix: админ-редактор — системные методы оплаты, реальные периоды тарифов, фильтрация на публичной странице

- Способы оплаты: загрузка из системного API вместо ручного ввода, toggleable чекбоксы
- Периоды тарифов: загрузка из period_prices через useQueries вместо произвольного ввода
- Публичная страница: глобальный список периодов, скрытие тарифов без цены для выбранного периода
- Локализация: добавлены ключи для 4 языков (ru/en/zh/fa)
