Feature Request: Add JWT Session Token Authentication to lakectl

[nopcoder]

Add support for lakectl to use JWT session tokens as an authentication method, providing an alternative to the current username/password authentication.

Problem

Currently, lakectl only supports username/password authentication, which:

• Doesn't support temporary access scenarios
• Can't integrate with external identity providers that issue JWTs

Requirements

• Add new configuration option as part of lakectl credentials to pass valid JWT - Example: LAKECTL_CREDENTIALS_SESSION_TOKEN
• Update authentication logic to prioritize token auth when provided

Benefits

• Better integration with temporary access patterns
• Alignment with python client support with session token
