feat(fusion_tasks): delivery-specific fields + reduced task types

Add delivery integration fields (delivery_id, sale_order_id,
portal_job_id, packages_count, weight_total, requires_signature,
requires_photo, coc_attachment_id). Reduce task_type selection to
delivery/pickup/return/rush with matching duration defaults.
Add delivery cascade in action_complete_task() that calls
delivery_id.action_mark_delivered() on completion.
