Pull Request Overview

This PR implements a Checkboxes List component as part of IBX-10621, introducing reusable components for handling lists of checkboxes and radio buttons. The implementation creates a new trait to share common functionality between radio button and checkbox list fields, along with corresponding TypeScript components for client-side interaction.

Key changes:

• Extracted common list field functionality into a reusable ListFieldTrait
• Added a new Checkbox\ListField component for handling checkbox lists
• Refactored existing RadioButton\ListField to use the shared trait
• Created TypeScript components for checkbox list field interactions

I've switched it off because it returns false-positive on https://github.com/ibexa/design-system-twig/pull/49/files#diff-914f9d057f37b814c2bb03196746b89ce20143f6ece03374618eb28d2472d225R76
Basically linter for TS is not able to recognize if method was bound in constructor (typescript-eslint/typescript-eslint#636), as it's our common way for binding I think switching it off globally is better than leave it globally and switching it off per usecase
