HIP-75: Remove the Mission Board Member Role

Use the WETH funds currently owned by the DAO to airdrop humans who have actively participated in POH. This is the most democratic way of allocating the funds, because even minorities will have a voice on how to use the DAO’s assets and we will avoid any fund allocation drama. Each politically active human supporting this HIP will receive around 0.04648-0.090 ETH (~82-165 USD at the time of writing).
