### SUMMARY When a dataset's metrics or columns are organized into custom folders, the folder assignments are lost after an export/import round-trip. Folder membership in the exported YAML references metrics and columns by UUID, but `ImportExportMixin.export_to_dict` did not forward `export_uuids` into the recursive child export, and the metric/column export schemas omitted `uuid`. Exported children therefore carried no UUID, so import assigned fresh UUIDs and the persisted `folders` structure kept pointing at the old UUIDs. On load, the affected metric was re-homed to the default folder. This change forwards `export_uuids` into the recursive child export and accepts `uuid` on the import column and metric schemas so the original UUIDs round-trip. Folder membership now survives an export/import cycle. There is no schema or database migration, and the behavior is unchanged when `export_uuids=False`. ### TESTING INSTRUCTIONS Added a command-level export then import round-trip regression test that asserts a metric's custom-folder membership is preserved. The existing dataset export/import unit and integration suites continue to pass. ### ADDITIONAL INFORMATION - [ ] Has associated issue: - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
