/api/v2/tasks/{id}/move_dependent

Shifts the task and its blocking dependent tasks by a number of working days.

The shift propagates transitively across blocking dependencies — every open task in the chain whose due date is set moves by the same number of working days. Non-working days are skipped using the organization's working-hours setting.

When booking validation is enabled and a shift would conflict with existing bookings on a moving task, the request fails with 422.
