Eduardo Figueroa 2c3d646611 feat(grafana): Add Docker logs dashboard for Loki
Add comprehensive Grafana dashboard for viewing Docker container logs
via Loki datasource.

Dashboard features:
- Real-time log streaming from all containers
- Log volume visualization by container
- Error detection and tracking
- Container and image filtering
- Text search with regex support
- Statistics panels (active containers, total logs, error count, log rate)

Includes:
- Pre-configured template variables for dynamic filtering
- Auto-refresh every 10 seconds
- Complete documentation with LogQL examples
- Troubleshooting guide
