refactor: remove old EditPlan flow from useGenerateVideo

- Delete generateEditPlan/updateEditPlan/getEditPlan old flow branch
- Remove buildEditPlanPayload (dead code, only used by old flow)
- Make previewTaskId required in UseGenerateVideoProps type
- Confirm generation now always uses POST /tasks/{taskId}/confirm
