[Copilot]

Pull Request Overview

This PR fixes an issue with incompatible converting to a nil pointer target as described in issue #4218. The changes refactor the conversion logic in the converter to avoid a duplicated type check and add unit tests for the fixed behavior.

• Refactored the Scan function in converter_scan.go to remove duplicate type checking and better handle nil pointer targets.
• Added a new unit test in gconv_z_unit_issue_test.go addressing issue gvar/Scan: When the field is a pointer, it does not take effect #4218.
