feat: separate About/Clients/Partners into /o-kompanii/ page, add IndexNow meta

- Create /[lang]/o-kompanii/ page with About, Clients, Partners sections
- Remove those sections from homepage (Hero + Services + FAQ remain)
- Update Header nav: "О нас" now links to /o-kompanii/ instead of /#about
- AboutSection: support standalone prop (h1 vs h2)
- Root layout: add indexnow-key meta tag (key from public/40c65b...txt)
