Refactor AST-136023: Use String.format for authentication status log message

Replace string concatenation (AUTH_STATUS + cxValidateOutput) with
String.format(PluginConstants.INFO_AUTHENTICATION_STATUS, cxValidateOutput)
to be consistent with the error logging pattern. Updated the unit test
assertion to verify the formatted string accordingly.
