Pull Request Overview

This PR fixes multiple bugs related to the Select component's behavior when using the multiple and checkAll options, specifically addressing issues with disabled options being incorrectly selectable or deselectable.

• Improves the check-all logic to properly handle disabled options by separating selectable and disabled items
• Fixes the filter option logic to use dynamic label keys instead of hardcoded 'label' property
• Updates the Option component to calculate selection states more accurately for check-all scenarios
