Updated Endpoints

Updated all endpoints to use Update() method of the model, instead of
trying to use the data from the REST object directly to update the
database.  WHen doing so, tracking gets busted in EFCore, so instead,
will go through and update all properties of a model from the database
object, with the data from the REST object.
