Users are no longer expected to manually set the status of an expense
and, instead, have to add payments to such expense to mark it as partial
or paid.
That means that the PL/pgSQL functions must not accept a status
parameter, the edit and new forms should no longer have a field for
the status, and that the expense list should no longer have the “quick
edit” for their status. That’s why it no longer should have a pointer
cursor, unlike invoice or quote status.
