🧹 Tobias: Refactor Payout#issue and supporting code

There was a number of things I didn't love about my implementation of
`Payout#issue`:

- I had added a `Tobias::Record` far earlier than necessary
- There were linter errors
- `Payout#payout_amount` felt redundant

This remediates those nose-wrinkles, and sets us up nicely for the next
test.
