Добавить Open Graph meta-теги для превью лендинга в мессенджерах.

- Добавлены og:title, og:description, og:image, og:url и Twitter Card в landing.html.
- Реализованы normalize_logo_url и build_landing_meta для абсолютных HTTPS-ссылок на логотип.
- landing_page передаёт meta-данные и единый logo_url в шаблон.
- Добавлены тесты нормализации логотипа и проверки OG-тегов.
