Integra Products e adapters S3/SMTP; corrige desvios pós-merge dos agentes

- Wire ProductsModule em app.module.ts; troca o import "deep path" que o
  agente usou (packages/database/dist/...) pela exportação correta via
  barrel (@eden/database), já que packages/database/src/index.ts é meu
  para editar durante a integração.
- S3/SMTP: troca leitura direta de process.env por loadEnv()/@eden/config
  (que não existia ainda quando o agente rodou no worktree dele).
- Resolve conflito de pnpm-lock.yaml (regenerado via pnpm install).
