Add transmission exporter, update dashboards for k8s services

- Add transmission-exporter sidecar for full metrics (speed, torrents, etc.)
- Add Prometheus scrape config for transmission metrics
- Update devpi dashboard to use blackbox probe metrics (status, response time, uptime)
- Restore transmission dashboard (will use exporter metrics)
