fix: improve field preservation in BaseTransformer and add Alias method to V13ToV14Transformer

- Updated BaseTransformer.transformDefault to properly preserve all fields during transformation
- Added dedicated Alias method to V13ToV14Transformer to handle alias node transformations
- Working on resolving colnames field preservation issue in numeric-549.sql test case
