Create a task

Creates a task and optionally assigns it to another user. The body must include a non-empty title and an assigneeID; valid status values are ASSIGNED, PROGRESS, and COMPLETED.

If assigneeID is 0, the task is assigned to you. If assigneeID is -1, the request is rejected with 400. The assignee must be a user you can assign work to (same subgroup or otherwise authorised). When the assignee is not the creator, an in-app notification is sent to the assignee automatically — no follow-up call is needed.
