Item: Change columns order on tracking for more readability

Display like this:

![image](/uploads/0e182e76a94c56eb450e8ef354a9c5c1/image.png)

Where we can easily read in listbox the history of item movements: 
```
   → A
A  → B
B  → C
```

instead of

![image](/uploads/24bea37097dc22c2eaedf323d049aeb3/image.png)


```
A 🠐 
B 🠐 A
C 🠐 B
```

( as always, this also enable coding style test )

I used a complex unicode character by mistake (🠐 instead of ← ) ... this might not display correctly...
