## Problem
The observability overview page fetched service health data by making
six separate calls to the generic \`logs.all\` endpoint with
hand-crafted SQL (via \`genChartQuery\`). This coupled the overview to
SQL internals and missed out on the purpose-built \`service-health\`
endpoint that accepts structured \`lql\` filters and a \`granularity\`
parameter.
## Fix
- Added \`/platform/projects/{ref}/analytics/endpoints/service-health\`
to \`platform.d.ts\`, including the \`ProjectServiceHealthResponse\`
schema and \`UsageApiController_getProjectServiceHealth\` operation.
- Created \`apps/studio/data/analytics/service-health-query.ts\` with a
\`getServiceHealth\` fetch function and \`useServiceHealthQuery\` hook
following the same pattern as other analytics query files.
- Added a \`serviceHealth\` key factory to
\`apps/studio/data/analytics/keys.ts\`.
- Rewrote \`useServiceHealthMetrics.ts\` to call the new endpoint per
service using \`lql\` selectors (\`s:postgres_logs\`, \`s:auth_logs\`,
etc.) and a \`granularity\` value derived from the selected interval
(\`1hr\` -> \`minute\`, \`1day\` -> \`hour\`, \`7day\` -> \`day\`). The
timeseries normalisation and chart data pipeline is unchanged.
- Updated the refresh handler in \`ObservabilityOverview.tsx\` to
invalidate the new query key prefix and removed the now-unused
\`postgrest-overview-metrics\` invalidation.
## How to test
- Navigate to a project's Observability > Overview page.
- Verify that the Service Health table loads data for all six services
(Database, Auth, Edge Functions, Realtime, Storage, Data API).
- Switch between the 1hr, 1day, and 7day interval selectors and confirm
the charts update.
- Click the Refresh button and confirm the charts reload.
- Click a bar in any chart and confirm navigation to the corresponding
logs page scoped to that time window.
- Confirm no regressions in the Database Infrastructure section (CPU,
RAM, disk, connections).
