Get Agent Observability Summary

Scope for a dashboard read.

project_ids and log_stream_ids are both optional: omitted means every project in the caller's org, and every dashboard-eligible run within it. Supplying either outside the caller's org is rejected rather than silently narrowed, so a wrong scope surfaces as an error instead of a quietly smaller number.

Both are typed as UUIDs so a malformed ID is rejected here, at the edge. As plain strings they reached Postgres as a comparison against a UUID column and surfaced as a 500.

One section's worth of cards plus the metadata describing how complete it is.

Availability semantics are frozen:

• at least one card succeeded → available=True; data_status is complete when every card succeeded and partial when some did not.
• every card failed → available=False, data_status=unavailable, and section-level degraded is set from the most common card failure. Cards remain in the payload with their own degraded payloads.
