[Trivial] Remove unused constants from resource/Fees.h

[scottschurr]

High Level Overview of Change

While reviewing other code I stumbled across a number of constants defined in resource/Fees.h that are unused anywhere in the code base. They did no harm, but it seems untidy to leave them lying around. This commit removes the unused constants.

I also tidied up some messiness left by clang-format.

Type of Change

• [x] Refactor (non-breaking change that only restructures code)

This pull request had become particularly stale. Since there have been no active reviews yet, I rebased the pull request to the latest develop.

I'll do the rebase. I should be able to get it done today.

Per offline discussion, the merge was actually easy, so I pushed it.

Presumably, this will be ready for merge once CI passes (unless it needs to be caught up to develop again).
