Budget edit person interaction - fix appointment type issue with select control in dialog

In KNS version, we have reference to actual property in tag file and were using DD definition via attributeEntry
 
Similar in KRAD p:dictionaryAttributeName was set and it doesn't work in dialog.
Created appointmentTypeCode and referencing the same in this PR.
We should remove appointmentType reference from DD later when we have Award budget in KRAD.
