KRACOEUS-7308: JPA work for budget

Yes. N is on and F is off in this case, which I think is extremely confusing when we also have Y and N and T and F converters. YN and TF at least make sense as a pair and they are exclusive which means they can share a simple converter. Throwing in N and F is really terrible as it mixes the 2 typical value sets in my mind. But on top of that, if you look up the existing converter code, it is confused as well. If a boolean true comes in it returns N(correct for this), but if a string comes in, it assumes T is the only "true" or on value. Which means it will never work.
