User story

As a developer, I want to query for tasks without a due date so that we can set one accordingly.

Background

By using a method like TaskQuery.withoutDueDate(), users can query for tasks that have not set a due date or have a null value set for the due date via API.

This will help clean up tasks that have no due date and ensure tasks are fulfilled on time.

Acceptance criteria

• I can query for tasks without a due date and receive a list of tasks I can use to process further.
• The option can be used in filters in the API, in tasklist, as well as in task searches in Cockpit
