feat(auth): подтверждение email + актуализация SMTP/Ollama конфигов

- Резенд письма верификации (/auth/resend-verification), модалка на
  фронте с поллингом статуса, страница /verify-email/:token
- SMTP переведён на собственный Postfix (mail.jze9mail.ru, STARTTLS,
  SMTP_TLS_VERIFY) вместо Yandex-заглушки в дефолтах и .env.example
- OLLAMA_URL и модель в worker-gpu синхронизированы с новым GPU-хостом
  (llama3:8b -> qwen2.5:7b, которой раньше не было на сервере)
