fix(i18n): spell the brand "Remnawave" instead of camelCase "RemnaWave"

Replace the user-facing 'RemnaWave' spelling with 'Remnawave' across all locale values (en/ru/zh/fa, 67 strings), t() display fallbacks, and code comments. Translation keys (refreshRemnaWave, ...) and code identifiers (RemnaWaveService, setRemnaWaveUuid, ...) are left untouched.
