fix: UI improvements and DingTalk attendance refresh for completed sessions

- DatePicker editors open immediately on double-click
- Student archive drawer hides empty studentNo parentheses
- Student add/edit form uses 2-column grid layout
- Table horizontal scrollbars show only on hover/focus
- Remove fake 近7日趋势 stats from attendance student detail
- Allow DingTalk refresh to update completed attendance sessions
  (late-arriving punches can now change absent → present)
- Switch dev command from concurrently to turbo run dev
- Remove concurrently/wait-on dependencies
