Fix monitoring API response format and add all metrics fields

Backend fixes:
- Обернул /host-metrics/recent ответ в {metrics: [...]}
- Обернул /alerts ответ в {alerts: [...]}
- Добавил все новые поля в /host-metrics/recent:
  - IOPS (disk_read_iops, disk_write_iops)
  - Throughput (disk_read_mbps, disk_write_mbps, net_in_mbps, net_out_mbps)
  - CPU advanced (cpu_per_core, cpu_steal, context_switches, interrupts)
  - Memory advanced (buffers, cached, available, swap)
  - Network advanced (packets, errors, drops)
  - Process metrics (process_count, thread_count, top processes)
- Добавил limit параметр для /alerts
- Добавил created_at поле для frontend совместимости

Frontend fixes:
- Убрал .reverse() из loadHostMetrics() (API уже возвращает в правильном порядке)
