Fix option min validation and formatter include

[sdraeger]

Summary

• Fix list minimum-length validation so lists shorter than the configured minimum are rejected.
• Fix FormatterDict.include() so it keeps requested keys instead of removing them.
• Add regression tests for both behaviors.

Testing

• python -m pytest tests/web/options/test_options.py tests/web/query/test_formatter.py

Thanks for the fix. I verified the patch and tests, and retargeted this PR to 1.1.x since that’s the intended release branch.
