Refactor ProfileControlsTF and ProfileObjState relationships

Updated property names and foreign key references in
ProfileControlsTF and ProfileObjState classes to improve
database relationship integrity. Added TFControls collection
to ProfileObjState and modified queries in ProfileObjRepository
to include related entities. Established relationships in
WFDBContext with cascade delete behavior.
