[$30] Additional Payments #430
Description
Background
We need to support this frontend feature via API topcoder-archive/topcoder-platform-micro-frontends-taas-admin-app#82
At the moment we can only process payments to the resource bookings for some amount of days worked via UI https://monosnap.com/file/HOmkcBnEVYmz3j0n32CcQ25TFQmQT5.
Sometimes managers would like to process additional payments which would not be counted for days. For this purpose, we would like to introduce additional payments which would not be counted as payment for working days.
Task
To indicate additional payments we would allow creating payments with days = 0.
Update endpoint to create payments POST /work-period-payments so it allows passing days = 0. Note, that if we pass days = 0 the payment should be created with days = 0 and should not be calculated automatically as it does now when we don't pass days
General Requirements
