_materialize_odfv used FeatureView.entities (entity names) instead of FeatureView.join_keys (actual join key column names) when building the entity DataFrame and querying the offline store during ODFV materialization. When an Entity's name differs from its join_keys (a supported, documented pattern), this caused materialization to query for a nonexistent column, breaking materialize()/materialize_incremental() for any OnDemandFeatureView with write_to_online_store=True sourced from such a feature view.
