feat(sync): add delivery cost, discount tracking and import settings

Parse delivery.total and discounts[] from GoMag JSON into new
delivery_cost/discount_total fields. Add app_settings table for
configuring transport/discount CODMAT codes. When configured,
transport and discount are appended as extra articles in the
Oracle import JSON. Reorder Total column in dashboard/logs tables
and show transport/discount breakdown in order detail modals.
