ServiceAnalyticsSpec class

Per-service analytics catalog: declares WHAT a service's analytics page shows, while the data source and AnalyticsDashboard handle HOW.

Composes the existing dashboard config types (ChartConfig, TableConfig) so a service UI can do:

const spec = ServiceAnalyticsSpec(
  service: 'payment',
  kpis: [
    KpiSpec('total', label: 'Payments', metric: 'payment_total'),
  ],
  charts: [
    ChartConfig.timeSeries('payment_total', label: 'Volume'),
  ],
  tables: [
    TableConfig.topN('payment_total', label: 'Top Routes',
        groupBy: 'route'),
  ],
);

AnalyticsDashboard(
  service: spec.service,
  title: 'Payments',
  metrics: spec.metricKeys,
  charts: spec.charts,
  tables: spec.tables,
)
