Chore(QuestFactory): decouple the claim fee and protocol fee accounting

[Quazia]

We want to very clearly document the flow of value in the protocol in the README.md and ensure that very precise understanding of the flow of value is possible entirely through event logging.

1. Document the value flow as it exists today
2. Check to see if any values are too heavily coupled to be separated from each other
3. Add additional events or transfers to make it more obvious what funds are going where and why
