Pull Request Overview

This PR applies the Rector rule ReduceAlwaysFalseIfOrRector to simplify conditional logic by removing dead code that always evaluates to false. The changes eliminate unnecessary null checks and redundant array type checks that static analysis has proven to be always false based on type declarations.

Key changes:

• Removed impossible null checks from Mage_Core_Model_File_Storage::_synchronizeHasErrors()
• Simplified redundant array check in Mage_Adminhtml_Block_Widget_Grid_Column::_applyDecorators()
• Updated PHPStan baseline to remove now-resolved false-positive warnings
