[FIX] pos_mercury: allow for 40 bit mercury invoice numbers

We generate the Mercury invoice number in JavaScript based on the uid
property of the order. That uid is generated by
Order.generate_unique_id() which generates a 12 digit number. A decimal
12 digit number can contain a maximum value of 10^12 - 1 which requires
40 bits to store. The issue is that Integer fields by default are backed
by a PostgreSQL integer type which is only 4 bytes. This means you can
end up with an invoice number you won't be able to store in the
database.

In order to resolve this we will update the field to be a Float field
instead which will result in a PostgreSQL double precision type which
allows values up to 10^308.
