Add reorg protection to LilNounsOracle contract

[nvonpentz]

Currently the LilNounsOracle contract ensures the by checking expectedBlockNumber == block.number. But we would have stronger guarantees in the case of a reorg if we checked if against a specific blockhash instead.

This is not easily possible because I believe the usePrepareContractWrite function we use from wagmi uses ethers js to fetch the gas estimate, which only only runs on the 'latest' block https://github.com/orgs/Lil-Nouns-Community-Engineering/projects/1/views/1. We need it to run on pending or else the gas estimate will result in a revert.

Potentially we can drop down to a lower level and use JsonRpcProvider.send directly and provide the correct blockTag there.
