feat(loyalty): report EnakPoint apart from money received

Keeps EnakPoint out of the money in on the payment method analytics
(docs/prd-point-coin.md F9, K7, PC-308), the one report that sums payments;
the daily transaction and profit-loss PDFs do not break payments down by
method.

summary.total_amount is now only money actually received. EnakPoint stays
listed as its own method, with points_used, and the summary adds
point_amount, points_used and total_with_points. Each method row says
whether it counts_as_cash_in, and the shares are of the money received, 0
for EnakPoint. The average order value still includes what EnakPoint paid,
since that is part of what the orders were worth. How EnakPoint is booked
waits on note N2.
