[FIX] point_of_sale: use currency precision to test if orders are paid

The test was made with an epsilon of 0.00001, which is precise enough to avoid
false positives, but allowing false negatives.
As a results, some orders can be incorrectly determined unpaid.
No (non-digital) currency has a precision higher than 0.00001,
but many currencies have a precision much lower (e.g the unit for ¥).
Also, we prepare for the future where all orders will be paid in Bitcoin.
