PR Summary

• Unified Behavior of ActiveRecord getAttributeLabel() Method
  The discrepancy in the getAttributeLabel() function from ActiveRecord has been addressed. Previously, primary model labels could override attributes of the related model only to a certain extent. Now, such overriding is permitted at all levels of relation nesting, enhancing consistency and predictability.

• Optimization of GridView
  An issue in the GridView was corrected. In certain situations, it was needlessly calling the 'generateAttributeLabel()' function from the Model to create label values that were never employed. This unnecessary operation has been fixed, enhancing the GridView's efficiency and performance.
