Successful Response

- CallPipelineMetricsSummary: Per-call aggregate pipeline metrics for the Insights tab.

  - `avg_e2e_latency_ms` integer, nullable
  - `turn_count` integer
  - `eou` StageLatencyStat: Distribution of one pipeline stage's latency (avg + percentiles). Percentiles come from Postgres ``percentile_cont`` over the same rows the average is computed on. Latency is a tail problem — the average hides the slow turns callers actually feel — so p95/p99 are the numbers that matter.
