fix(dashboard): add aggregated resource usage stats to the dashboard

- Aggregate CPU, memory, and network stats across all running containers
- Extend ISystemStatus.docker with resource usage fields
- Fix getContainerStats Swarm service ID fallback
- Wire dashboard resource usage card to real backend data
