feat(landing): Russian default + SEO head, icons and OG card

The landing now always opens in Russian (saved 🌐 choice still wins) — browser-language detection made the indexed content nondeterministic (Googlebot renders with en-US). landing.html gains the static Russian SEO head: title/description, canonical pinned to the production origin, Open Graph card (Telegram/VK link previews), twitter:card, JSON-LD, theme-color and the favicon set; the SPA shell turns noindex and its tab title becomes «Эрудит (Скрэббл)». New assets/icons generator (same tile design as the VK loader) produces favicon.svg/ico, apple-touch-icon.png and og-image.png into ui/public/, plus robots.txt.
