feat(i18n): migrate all hardcoded Russian text to i18n

- Replace all hardcoded Russian strings with t() calls across 30+ files
- Add ~500 new translation keys to all 4 locales (ru, en, zh, fa)
- Convert module-level config objects to labelKey pattern
- Remove Russian fallbacks from t() calls (fallbackLng handles it)
- Replace DeepLinkRedirect custom i18n with standard t() calls
- Fix subscription.servers key collision (string vs object)
