Quite a big commit, so will break up changes:

Contracts and tests have been split into separate folders The JEWEL contracts have been renamed to have a 'h' in them (for harmony). Otherwise we get namespace collisions. We shouldn't need be using these contracts in the front end so I don't see any issue doing this

Tests are split up. because of issues getting RPC to work, we will need to do tests individually- brownie test tests/dfk will run dfk tests and brownie test tests/harmony will run the old tests

I made some changes to the contracts:

• centralbank now has a separate keeper (separate to owner/fee wallet)
• gmcrystal is just updated name/symbol
• pawnshop v2 has necessary checks to prevent issues with frontrunning/overpaying fees
• utxo has removed profiles (no longer utilised)

this updates the back-end for the api to correctly get the redeemor for anyone that redeems via router

back-fill is not necessarily (it will just incorrectly attribute the first few stashes)

wagmi package doesnt actually prevent transactions on the wrong chain this prevents you from accessing site when you are using the wrong chain this is just a temporary fix to prevent anybody signing transactions they didnt intend to (shouldn't cause any issues other than wasted gas but still important to fix) it also offers the option to change network This is really ugly with css so should probably review this before deploy

When a user mints from a stash, deposits more, and doesn't mint, the stash becomes unredeemable. This is why the forceRedeemUTXO function exists, to forcibly mint the rest to the minter and then to allow the user to redeem. The UI should be able to handle this.

• UI should show when nominalCombinedValue of a UTXO is different to the mintedFrom value
  • Important, because the true cost is based on nominalCombinedValue, but the UI, on the JewelStash, only shows the amount minted due to the way the API works
• Once user is presented with true cost, they should be able to still redeem, but the UI should call the forceRedeemUTXO function

• [ ] Create CentralBankGovernor contract, which will become the owner of the CentralBank
• [ ] CentralBankGovernor is Ownable
• [ ] CentralBankGovernor has list of keeper addresses
• [ ] CentralBankGovernor allows pass-through calls to CentralBank for all functions (with same access control) EXCEPT for withdrawCentralBankJewel, which has modified access control to allow keepers to also call it
• [ ] (#22) Create basic keeper bot to perform fee buybacks

Step 1: ensure all event scanning is idempotent, ensure concurrent event scanners dont interfere with each other (add backfill runtime flag that doesn't check last scanned block)

Step 2: track last scanned block on a per feature basis, allow for resetting based on some sort of increasing number
