refactor: remove unused method receiver

[deepsource-autofix]

This PR refactors the mockSpinner methods to eliminate unused receivers and clean up indentation.

• Unused method receiver: The mockSpinner methods Fail, Success, and Stop originally declared a named receiver (m) that was never used. The patch replaces these named receivers with unnamed pointer receivers to adhere to Go best practices and remove compiler warnings. Additionally, the indentation of the Stop method’s return statement was standardized for consistency.
