-- `ManagedDatabaseClient.fetch_table` now carries the `X-Database-Id` scope header on the result poll, the query-run poll, and the Arrow fetch — not only on the query submit. Results of database-scoped queries are themselves database-scoped, so every read against an existing synced table (merge/append loads, dlt state restore) failed with `400: Bad Request` once the table had data (dlthubworker#70).
