Remove Default /debug Endpoint

[Format-C-eft]

This MR proposes the removal of the default /debug endpoint, which is automatically registered by the net/http standard library. The /debug endpoint exposes debugging information that may include sensitive data, posing a potential security risk in production environments.

Key changes:

1. Removed the registration of the /debug handler via http.DefaultServeMux.

Benefits:

1. Eliminates a potential security vulnerability related to the exposure of debugging information.
2. Reduces the risk of data leakage in production environments.

Please review the changes and provide feedback.
