A new Metrics page for browsing and comparing metrics

Observability has been added to the sidebar. Its Metrics page lists the metrics collected from your connected clouds and lets you explore them over time.

• Metrics are shown as cards with sparklines. You can search by name or tag and mark favorites
• Selecting a card opens a detailed time series. Statistics such as minimum, maximum, average, and standard deviation are shown, and the data points for the displayed period can be exported as CSV
• Metrics can be overlaid on a single time axis for comparison — up to 5 plotted at once, with up to 10 held as candidates. For series with different units or magnitudes, switching the vertical axis to “Change” makes them comparable on the same scale
• Runbook and AI agent executions can be overlaid on the chart, so you can line up when a value moved with what was running
• Each metric’s collection state is shown in both the list and the detail view: collecting (up to date or delayed), awaiting first data, collection stopped, no collection target, or connection error. Sorting by collection state brings the ones needing attention to the top
• How far back you can look is governed by the data retention period of your plan
