KtFieldNumber: permit having value over maximum if isOverMaximumAllowed is true

[RueRivoli]

Is your feature request related to a problem? Please describe.
In some case in MES, we want to allow the user to specify a value over the maximum with the KtFieldNumber component.
This would be needed in the feature called "overquantity" which can be described as:
"I want to produce more parts than ordered to account for faulty parts or to keep some parts in the storage".

Describe the solution you'd like
We want the value of the field number to go over the maximum in this case only.
Potentially a property isOverMaximumAllowed to provide to the KtFieldNumber to be true to allow this behaviour.
Then the user would see 7/5 for example and understand : I produce 2 more parts than the customer ordered.

Describe alternatives you've considered
Other alternatives in the past were about different designs:

• showing quantity selected in a KtFieldNumber with no maximum and outside of the quantity number the total of ordered parts but this is the favourite option.
