fix: remove redundant identity check in file parameter test

- Replaced 'assert file_param is not None' with meaningful assertions
- Check file_param.description and hasattr for json_schema_extra
- Addresses SonarCloud quality issue S5727: comparison to None should not be constant
- Improves test meaningfulness and code maintainability
