don't copy UPS tracking URL + shipment ID when copying picking

* per-item value_amount should be a string, not a float value
* total_value_amount should be an integer, not a float value

"Error in Shipment Data: Bitte geben Sie die Versandkosten für die
Zollabfertigung an. Der eingegebene Wert ist zu lang und wurde gekürzt."

Closes: SYS#5510
