- Complete tasks now displayed in scroll view alongside unfinished tasks
- Priority order: completed tasks first (by finished_time desc), then unfinished (by order asc)
- Time picker-style scroll: wheel scroll snaps per task, center item gets visual focus
- Landscape mode (>=1024px): scroll view + edit panel side by side, panel always visible
- Portrait mode: edit panel slides in from right on tap
- Fixed flex layout so scroll view and edit panel align perfectly in height
