## Description

Enable moving tasks within/between sequences; call the move endpoint to update dependencies and refresh state.

## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Dragging (or keyboard) moves tasks using join semantics: set moved deps to previous sequence only; other tasks unchanged
- [ ] #2 Moving to Unsequenced allowed only if task is isolated; otherwise show clear error and do not move
- [ ] #3 After move, refresh state from server and preserve scroll/focus; provide success feedback
<!-- AC:END -->
