Use real git commit dates in sitemap lastmod values
Static routes had no lastModified at all, giving Google Search Console no freshness signal for the site's core marketing pages. Derive lastmod per page from git log on its source file, matching the fix already shipped in the smbcloud monorepo's copy of this site. Verified against real next build output.
