Runner CI job machine metrics and dashboard charts

Tuist Runners CI jobs now display machine metrics in the dashboard. The job detail page has a new Metrics tab with a five-chart grid covering CPU, Memory, Network, CPU I/O Wait, and Storage, plus a compact CPU/Memory/Network row in the Overview card for an at-a-glance read. Hovering a step on the Overview shades that step’s time window across the charts so resource usage can be correlated with the step that produced it. Charts use uniform percent axes and straight point-to-point segments to show real spikes and dips, and the dashboard includes an empty state for jobs without samples yet. Data is collected from busy runner Pods via a controller-side collector, ingested through a new server endpoint, and stored in a ClickHouse time-series table.
