List usable structured destinations
Returns the subset of [mongodb, postgres, objectstore, snowflake, databricks] usable in this deployment. Drives the pipeline wizard’s and Assistant’s destination picker. Two availability semantics on purpose: the self-hosted destinations (mongodb, postgres, objectstore) are live-probed — secret presence alone isn’t a reliable signal because the compose stack seeds their secrets even when a service is disabled; the external SaaS destinations (snowflake, databricks) have no local service to probe, so they are included when any Platform secret carries a complete credential set for them.
