Add tools/scripts coverage to the Python linting task

[coderabbitai]

Summary

The Python linting task does not lint Python scripts under tools/scripts.

Add tools/scripts to the Python linting task so that repository scripts receive the same automated lint checks as other Python code.

Rationale

tools/scripts/docker/resolve-huntsman-e2e-endpoint.py required manual linting because the current task does not include tools/scripts. Automated coverage will detect lint violations in these scripts during normal validation and CI.

Affected areas

• Python linting task configuration
• tools/scripts/**

Acceptance criteria

• The Python linting task includes applicable Python files under tools/scripts.
• The task runs the existing Python lint tool and configuration for these scripts.
• CI executes the updated Python linting task.
• Existing Python linting behaviour remains unchanged for currently covered paths.
