feat: métriques réseau+hardware serveur+dashboard + API /agents/{id} + iperf3

Browse Source 
Serveur:
- Modèles Go: NetworkInterface, HardwareInfo dans Agent + AgentMetrics
- DB: migrations network_info_json + hardware_info_json dans agents
- UpsertAgent: stocke les données lentes si présentes dans le payload
- GetAgents: désérialise network_info_json + hardware_info_json
- GET /api/agents/{id}: endpoint single agent
- docker-compose: service iperf3 (port 5201)

Dashboard:
- Popup détail: section RÉSEAU (tableau interfaces: type, vitesse, MAC, WoL, iperf3)
- Popup détail: section HARDWARE (carte mère, CPU, RAM slots/type/vitesse)
- CSS: .net-table/.net-row pour le tableau réseau
- Font-size global appliqué sur html root (au lieu de body)
