Nicolas Cantu 90ff8282f1 feat: Implémentation système de commissions systématique et incontournable
- Création lib/platformCommissions.ts : configuration centralisée des commissions
  - Articles : 800 sats (700 auteur, 100 plateforme)
  - Avis : 70 sats (49 lecteur, 21 plateforme)
  - Sponsoring : 0.046 BTC (0.042 auteur, 0.004 plateforme)

- Validation des montants à chaque étape :
  - Publication : vérification du montant avant publication
  - Paiement : vérification du montant avant acceptation
  - Erreurs explicites si montant incorrect

- Tracking des commissions sur Nostr :
  - Tags author_amount et platform_commission dans événements
  - Interface ContentDeliveryTracking étendue
  - Traçabilité complète pour audit

- Logs structurés avec informations de commission
- Documentation complète du système

Les commissions sont maintenant systématiques, validées et traçables.
