Offer department-owned task types in the shot/asset Add Task dropdowns

ShotDetailPanel and AssetDetailPanel now merge department task types
(filtered to shot/asset departments respectively) into the flat task
type list shown in "Add Task", so types like Animation's blocking or
Composite's first_pass are selectable at creation time instead of only
via editing a task's type afterward. No backend change needed since
task creation already derives department from an owned task type.
