Проблема:
- health-check-alerting.sh использовал --mode restore-size
- Показывал 23.33GB вместо реальных 6.51GB
- False positive alert о превышении лимита R2 (10GB)

Решение:
- Изменен режим на --mode raw-data для получения фактического размера
- raw-data показывает реальное использование R2 с учетом дедупликации
- Добавлены пояснительные логи "(raw storage with deduplication)"

Проверка:
- Cloudflare UI: 7.05GB ✅
- restic stats raw-data: 6.514 GiB ✅
- restore-size: 23.330 GiB (размер при восстановлении всех снапшотов)

Теперь скрипт корректно показывает:
✅ R2 storage OK: 6.51GB / 10GB (raw storage with deduplication)
📦 R2 snapshots: 3 (policy: keep 3 daily + 1 weekly)
