KRACOEUS-7807 fixing budget columns maintenance doc

KRACOEUS-7807 adding starting bean id statement, so datadictionary services can read it, and make use of it in budget columns maintenance docs
Instead of this, can you change the budget columns maint doc to look at PropDevBudgetExt? This class should be abstract and we would like to make it abstract eventually. And technically it is more correct to point to the propdev version in any case since thats where editable columns are used.
