Fix portal SEO, Korean copy, and favicon

Custom-domain base URLs included the request path, so
canonical/hreflang doubled routes; emit SEO links only with
an absolute origin. Rewrite Korean mismatch strings to avoid
literal particle parentheses, rename HtmlLang to HTMLLang, and
ship public favicons so Vite no longer 404s the fallback icon.
