fix: supprime social proof fake, fixe bannière + navbar, popup mobile

- Supprime SocialProofTicker (notifications fake visiblement artificielles)
- Navbar passe de fixed à sticky pour s'empiler correctement sous la bannière
- Bannière d'annonce responsive (texte court sur mobile, bouton close adapté)
- Hero: réduit le padding top (plus besoin de compenser un navbar fixed)
- Exit-intent popup fonctionne sur mobile (trigger au scroll-up après 60% de page)
- Popup responsive: tailles ajustées pour mobile
