Refactor GridScheduleGenerator and related components to improve cursor management and group handling

Updated the GridScheduleGenerator to reset cursors for slots with no aired positions, ensuring proper state management during rebuilds. Introduced a new method, ResetUnairedCursorsAsync, to handle cursor resets effectively. Enhanced the handling of interstitial groups in the scheduling process, preventing them from being included in slots or fallback groups. Updated related tests to verify the correct behavior of these changes, ensuring robust scheduling logic and accurate group categorization.
