[BIP-455] Assisting DNS hack victims

Payload with PR

https://github.com/BalancerMaxis/multisig-ops/pull/568

Intro

Following the developments after the DNS hack reported here, and given the current framework proposition on BIP-443, this proposal seeks to compensate users affected by the frontend attack by refunding 75% of their lost funds, taking BIP-443 as precedent.

Motivation

As of the time of writing, only 5 (five) users have reported loss of funds to the Balancer Maxis or other community contributors, to a total amount equivalent of $319,228,08 USD at the time of the attack.

From that amount, a portion of $157,075 USD belonging to auramaxi.eth was taken care of immediately after the approval of BIP-443. The four other users manifested their will to claim for a refund of the remaining $162.153,08, taking the 25% cut under the same precedent set on that proposal, for a total of $121.614,81 USDC on mainnet.

Given that the original proposal needed further developments (volunteer committee, Google form and public announcement), this BIP must be treated as an exception in case BIP-443 sees any traction in the future. However, it's only appropriate to take from the 350k previously approved by governance as max budget for compensations.

The addresses below are verified, known and damaged wallets, who will be providing on-chain signatures for wallet verification referencing this BIP in the comments below, along with a statement forgoing all further claims to restitution. The amount to be sent is 75% of the total lost by these wallets during the attack period (including amounts stolen and angel drainer contract fee), which can be verified on-chain and cross ref with @gosuto spreadsheet here.
