Added missing translations for permissions of margins module

bug #1179

if there's a delivery date (date_livraison) then use it instead of the validation date (date_valid) to check if we need to display a warning or not...

For example, if we are in Septembre and there's an order that was validated in june but its delivery date is set to november then a warning is not necessary, since there's nothing to do but wait for the order to be delivered.

Ex draft bill for november :

{mm} = 11
On validation, number -> FC131160 instead of FC131112
