Enhance ChoresPage accessibility and functionality

- Added ARIA roles and attributes to buttons and modals for improved accessibility.
- Updated chore types and properties in the Chore interface to allow for null values.
- Refactored chore loading and filtering logic to handle edge cases and improve performance.
- Enhanced calendar and list views with better user feedback for empty states and loading indicators.
- Improved styling for mobile responsiveness and dark mode support.

These changes aim to enhance user experience, accessibility, and maintainability of the ChoresPage component.
