fix: correct duty list scrolling behavior and simplify current duty check

- Removed unnecessary condition for determining if a duty is current, streamlining the logic.
- Refactored the scrolling functionality to ensure the view correctly focuses on the current duty or today's block.
- Improved code clarity by consolidating the scroll target logic into a reusable function.
