Pull Request Overview
This PR fixes a bug where plucking localized and aliased fields was broken due to incorrect field name resolution. The fix ensures that database_field_name is called after removing _translations from field names in the pluck operation.
- Adds comprehensive test coverage for pluck operations with localized and aliased fields
- Fixes field name resolution in the pluck method by properly handling aliased localized fields
- Updates model definitions to support the new test scenarios

The test data setup doesn't match the expected values. The setup creates 'english-text'/'deutsch-text' but the tests expect 'Kyoto'/'京都'. This will cause test failures.

This PR adds tests for pluck cases, both of which are broken on master.
I have fixed the non-embedded case, however, I think the best fix will patch
#cleanse_localized_field_namesso that it correctly callsdatabase_field_nameafter removing_translationsfrom the name.To test:
