Add accepting_usr to IDL to fix reporter field
In the reporter interface, the view 'Payments: Brick-and-mortar' is
missing the 'Accepting User' field, which is present in the similar view
'Payments: Desk'. This field is already present in the database view and
is simply missing from the IDL. Since it is needed for certain kinds of
reports, this commit adds the missing IDL fields. It also adds the
missing 'reporter:datatype' to an existing instance of the IDL field.
