[fix] Fix relationship reference serialization for Atlas API compatibility

- Ensure typeName is preserved in relationship attribute dicts (omit_defaults was dropping it)
- Wrap qualifiedName in uniqueAttributes for ref_by_qualified_name references
- Add Folder.creator() and Query.creator()/with_raw_query() factory methods
- Fix insights_test.py to use client.asset.find_connections_by_name
- Handle data_contract_latest as dict or object in data_mesh_test
- Revert eager nested entity conversion (caused validation errors)
