Beta — may change; breaking changes are coordinated with affected
customers. Suitable for evaluation, not production reliance.

Lists services, one row per service, each carrying a closed RED metrics
snapshot under redMetrics. Filters are exact-match on serviceName,
environment, and serviceNamespace; an omitted filter matches every
value of that dimension.

When expand=true, each row's redMetrics.series[] additionally
carries a per-bucket time series across the query window; read the
bucket cadence from the spacing between consecutive
series[].timestamp. When expand is false or omitted, series is
absent (not null, not an empty array).

Zero matches return 200 with services: [] and meta.totalCount: 0.
meta.totalCount is -1 when an exact count is too expensive to
compute; in that case paginate by advancing offset until a page
shorter than limit is returned.

Response size grows with the number of rows on the page and, when
expand=true, with the number of series points per row. A wide window
combined with expand=true can therefore make a single page exceed the
server response-size limit and return 413 PayloadTooLarge. Recover by
narrowing the time window or requesting a smaller limit. limit is
never rejected for being too large: it is clamped to its maximum
server-side, and to a lower maximum when expand=true.
