fix(coding-agent): corrected config display to render arrays and objects as JSON

- Improved config display formatting to properly render arrays and objects as JSON instead of `[object Object]`.
- Enhanced type display in config list output to show correct type indicators for number, array, and record settings.
- Added test coverage for record settings rendering in config list output.
