🔒 [security] Redact sensitive driver_details in EnvironmentConfig repr

[mysticBliss]

🎯 What: The vulnerability fixed
Redaction of sensitive driver_details (which may contain credentials) from the EnvironmentConfig class's __repr__ method.

⚠️ Risk: The potential impact if left unfixed
Sensitive data like database passwords or connection strings could be exposed in application logs when the EnvironmentConfig object is logged (e.g., during engine initialization), potentially allowing unauthorized access to data systems.

🛡️ Solution: How the fix addresses the vulnerability
The __repr__ method was updated to replace the actual driver_details dictionary with the string <REDACTED>, ensuring that sensitive information is never included in the string representation of the object while still providing context about other non-sensitive fields.
