Добавить пререндер, партнёров, реквизиты, SEO-улучшения

- SSR-пререндер через Vite + react-dom/server (entry-server.jsx, scripts/prerender.mjs)
- Секция партнёров: RU-CENTER, REG.RU, МТВ, КОНТУР
- Реквизиты компании в футере (ИНН, ОГРН, банк)
- Копирайт с 2011 года
- Логотип увеличен (h-8→h-12 навбар, h-7→h-10 футер)
- favicon.ico пересобран с 16×16, 32×32, 48×48 из logo.png
- og:image и twitter:image переключены на .png
- apple-touch-icon.png и og-image.png сгенерированы через sharp
- SSR-safe: localStorage и window.location проверяются на typeof
