fix(migration): суммы документов МойСклада как decimal (приходят «900000.0») + GET статуса job

МойСклад отдаёт sum/cashSum/price как число с точкой (900000.0) → long не парсился
(«JSON value could not be converted to System.Int64»). Поля DTO → decimal. Плюс
GET /api/admin/moysklad/jobs/{id} для наблюдения за прогрессом/ошибками переноса.
