Add auto-detecting header-alias layer (_EXPORT_HEADER_ALIASES) so
import_drivers_csv ingests the raw Tracksolid Pro device export
(Title-Case headers: IMEI, Driver Name, LicensePlateNo., Model,
Vehicle Model, …) in addition to the original snake_case schema-mirror
CSV. Add customer_name/device_group to the write set, extend the
driver-placeholder skip list (Unassigned/UG/UG Crane), and exclude
activation_time/expiration/device_group (date-only/casing churn that
would degrade precise API-set values).
Used to apply the 260625 telematics quality-check file: 152 devices
updated (device_name, driver_name, plate, vehicle type, depot_address).
