Diff should always use a red/green background and display unchanged values.

unique values(name/descprition, ...) display two lines :

old Value: before
new Value: after

We should display only the two lines without the prefix (old/new value) and no strikethrough text

On a list display currently it displays:

old value: A, B, C
new value: A, B, D

should be displayed like this :

  A
  B
- C (in red)
+ D (in green)

If the value has not changed, the value should be kept instead of not showing anything.
