[BOOST-4688] viability testing: register an ENS domain

[mmackz]

Description

Viability tests for registering an ENS name.

• added NameRegistered to event signatures

Used Sepolia for this as it is the only other chain ENS supports outside of mainnet which is expensive to use for test purposes.

The tests are currently not working. It errors out when trying to send the transaction (line 166 in test file).

Serialized Error: { details: 'Error: VM Exception while processing transaction: reverted with an unrecognized custom error (return data: 0xcb7690d70eaeb279d6cd9d8e9917cb69abaf18adb26cfa42ee7fa24301ac6a915d504f4b)'

      const testReceipt = await walletClient.sendTransaction({
        data: inputData,
        account: boostImpostor,
        to: targetContract,
        value: 408279452054767655n,
      });

I think this may be because there is a commit transaction (and 60 second wait) that needs to be made before the actual registration can happen. Either that, or the name is already registered? Im not sure. Although I set the block to a historical block from before I registered the name, the hardhat logs indicate that it is using recent blocks in the transactions.
