fix(net): unable to pass HttpStatusCode

[j2rong4cn]

错误的使用errors.Unwrap errors.Unwrap并没有fallback机制

[Copilot]

Pull Request Overview

This PR fixes an issue where HttpStatusCode couldn't be properly passed through error unwrapping by replacing errors.Unwrap with a custom errs.UnwrapOrSelf function that provides fallback behavior.

Key changes:

• Introduces a new UnwrapOrSelf function that returns the original error if unwrapping fails
• Replaces three instances of errors.Unwrap with the new fallback mechanism in HTTP serving logic
