fix: sanitize error logs

[hanakannzashi]

Removed potential information leakage code from the error log

[Copilot]

Pull Request Overview

This PR systematically removes detailed error information from logging statements across the codebase to prevent sensitive data exposure in logs. The changes focus on sanitizing error logs while maintaining error details where they are returned to error handlers or included in error responses.

Key changes:

• Replace map_err(|e| { tracing::error!("message: {}", e); e }) with inspect_err(|_| { tracing::error!("message") })
• Remove error details from logging statements while preserving them in returned error values
• Convert unused error bindings from Err(e) to Err(_) where error details are no longer logged
