Logo du site, favicon et contrôle des inscriptions

SiteSettingsService : persistance JSON dans storage/app/site_settings.json
  (pas de migration DB — survit aux mises à jour sans table supplémentaire)

Logo :
- Upload admin (PNG/JPG/SVG/WebP, max 2 Mo) → storage/app/public/site/logo.{ext}
- Favicon <link rel="icon"> injecté dans app.blade.php et guest.blade.php
- Logo affiché dans la barre de navigation (h-8, object-contain)
- Logo affiché sur la page de connexion (guest layout)
- Page d'accueil welcome.blade.php entièrement refaite : logo + bouton connexion
  (remplacement du template Laravel par défaut)
- Suppression du logo possible depuis Admin > Paramètres du site

Inscriptions :
- Désactivées par défaut (registration_enabled=false dans site_settings.json)
- RegisteredUserController : redirige vers /login si inscription désactivée
  (GET /register → redirect + message ; POST /register → abort 403)
- Page d'accueil : bouton "Créer un compte" masqué si inscriptions désactivées
- Admin > Paramètres du site : toggle checkbox pour activer/désactiver

AppServiceProvider : partage $siteLogoUrl et $registrationEnabled avec toutes les vues

Navigation : lien "Paramètres du site" en bas du menu Administration
