fix(i18n): починка плейсхолдеров и переводов в zh/fa/en локалях кабинета

Аудит локалей кабинета с русским в качестве эталона.

Битые {{плейсхолдеры}} в zh/fa (рендерились как литеральные скобки,
теряли значение или дублировали то, что и так выводится в JSX):
- gift.sentTo / gift.activatedBy: неверное имя переменной
  ({{name}} → {{recipient}} / {{username}})
- dashboard.devicesConnectedUnlimited: {{count}} → {{used}} (+ «без лимита»)
- dashboard.maxUsage, gift.deviceCount, gift.activateSuccessDesc: потерянные
  значения возвращены
- dashboard.expired.activeUntil, subscription.trialInfo.remaining: убран
  {{date}}/{{count}} — значение выводится отдельным элементом
- trialInfo.description, trialOffer.freeDesc/paidDesc, gift.shareText:
  переписаны без {{days}}/{{price}}/{{code}}, которые код не передаёт
- wheel.payWithStars: одинарные {stars} (i18next их не подставляет) убраны

Мисперводы zh/fa (разошлись по смыслу с ru/en):
- subscription.cta.*Hint, expiredBanner.selectTariff, trialUpgrade.description,
  reduceDevicesDescription, menuEditor.customLabelsHint, myGiftsEmptyDesc,
  partners.settingsFields.*, remnawave.overview.bandwidth, shareModalActivateVia

fa admin.pinnedMessages: 40 строк были на английском → переведены на фарси.
zh common.all: 'All' → '全部'.
en admin.broadcasts.subtitle: устаревшее «History and management» →
соответствует ru «Массовая отправка сообщений пользователям».

Плейсхолдеры и синхронность en/ru проверены (locales.test.ts).
