refactor: use errors.New to replace fmt.Errorf with no parameters & fix typo

[LesCyber]

1. use errors.New to replace fmt.Errorf with no parameters
2. fix typo
3. unify the error handling methods that are different from the project style

Replaced fmt.Errorf with errors.New in cases where formatting is not required. This reduces unnecessary function calls, leading to slightly improved performance and cleaner code.
