Read execution log events for a product in one call. Without streamName, resolves the most recently active stream in the chosen log scope and returns its events; with streamName, behaves like GET /products/{productId}/execution-log-streams/{streamName}/events.

Which logs? Two log scopes, selected via onlyTestRuns:

• production (default, onlyTestRuns=false) — populated by real shipment pricing.
• test-run (onlyTestRuns=true) — populated by operator-UI 'Test product' / 'Test brick' invocations AND the REST POST /products/{id}/execute endpoint.

Test-case-run logs are NOT here. POST /products/{id}/test-cases/run returns its logs inline in the response logs[] field; they are not persisted to either log group.
