Copy a folder

Creates a new folder by copying a source folder (template_id) into a target project. By default only the folder shell is copied; enable the copy_* flags to duplicate its task lists, tasks, and their details.

Required: name, template_id (the source folder), and project_id.

Copy flags

Copying cascades through levels: enable copy_task_lists to bring over the folder's task lists, then copy_open_tasks / copy_closed_tasks to bring over their tasks, then the per-task flags to bring over task details. All copy_* flags default to false.

Enabling tasks without copy_task_lists returns 422 (task_lists_required); enabling any per-task flag without a tasks gate returns 422 (tasks_required).
