Subject: Refactor checkbox-list custom field implementation

- Replaced the PluginIcon with EnumerationField in the custom field registration.
- Introduced CheckboxListDefaultInput component for handling checkbox list inputs.
- Updated the admin interface to include new settings for the checkbox-list custom field.
- Enhanced server-side registration to support resizable input size for the checkbox-list.
