feat(abonnements): paliers LLM Essentielle/Premium, admin modeles par forfait, statistiques revenus, emails marketing
All checks were successful
Deploy to Production / Build and Deploy (push) Successful in 2m51s

- Gamme officielle : Essentielle (Pro) = deepseek-v4-flash, glm-5.3-flash,
  minimax-m3 ; Premium (Business) = claude-sonnet-5, deepseek-v4-pro, glm-5.3
- Routage reel : le modele employe suit le palier IA du forfait (reglages
  admin > defaut du plan), garde anti-croisement de palier
- Nouvelle page admin « Modeles & abonnements » (matrice forfaits/paliers,
  modele par defaut, catalogue OpenRouter)
- Statistiques enrichies : revenus (30 j + total), MRR estime, credits,
  liste d'attente, paliers utilises
- Nouvelle page admin « Marketing » : audiences avec compteurs, apercu,
  envoi test obligatoire, historique, desabonnement public + en-tetes
  List-Unsubscribe ; .gitignore pour les donnees d'execution
- Interface (accueil + tarifs) alignee sur la gamme, 13 langues completes
- Tests : routage par palier (fonction + tache), marketing, revenus en base
