[Android] Scheduled pot withdrawals pot summary is wrong

A scheduled pot withdrawal will be categorised as a negative balance “into pots”. This should instead have a positive value and the text should be changed to “out of pots”. However, I outlined what I think is a better solution in this ticket

Details to reproduce:
Set up a scheduled pot withdrawal. Wait for money to be withdrawn on the specified day. Go to the spending tab, and view the summary at the top.
