feat: Refactor ScheduleModal to support interval scheduling with date input and deadline toggle

- Updated ChoreSchedule model to include anchor_date and interval_has_deadline.
- Refactored interval scheduling logic in scheduleUtils to use anchor_date.
- Introduced DateInputField component for selecting anchor dates in ScheduleModal.
- Enhanced ScheduleModal to include a stepper for interval days and a toggle for deadline.
- Updated tests for ScheduleModal and scheduleUtils to reflect new interval scheduling logic.
- Added DateInputField tests to ensure proper functionality and prop handling.
