Fix CI tests and coverage

[arr00]

This PR fixes CI testing and coverage. The coverage provider switches to codecov since codecov provides better support for multiple coverage files (hardhat and foundry).

Contracts that are no longer utilized by Compound DAO in production have been removed along with the associated tests--all contracts that are still used in production remain untouched.

I think most of the changes were just formatting but I did have 1 question on where some storage variables ended up moving to.

Also, can you update the .prettierrc you used when formatting all of these files. There is definitely a line width since most of the changes were just from shorter lines I think? I would say let's check in the current on you got so future folks can all be consistent and things are a little easier to review.

Where did all of this storage stuff move to? Or were we just no longer user it?

[arr00]

We aren't using it anymore

I believe these are the default settings for prettier? I didn't make any changes locally to .perttierrc. The previous PR didn't follow the existing prettier config in the repo.
