feat(browse): fusion Parcourir + Catalogue en une seule page

- Barre de recherche intégrée dans BrowseComponent
- Mode navigation (tuiles) si recherche vide, mode liste (cartes) si texte
- Debounce 400ms + pagination pour les résultats de recherche
- Suppression de l'entrée "Catalogue" du menu de navigation
- Redirection /catalog → /browse (vieux liens toujours fonctionnels)
