[BIP-825] Enable YieldFi yUSD/USDC gauges on Balancer v3 Arbitrum new pool deployment

PR with Payload

https://github.com/BalancerMaxis/multisig-ops/pull/2006

Summary:

This is a proposal to enable the root gauge https://etherscan.io/address/0xc77AC1AE3434260baeFcE0e23582c1249392D12d on Ethereum, [which redirects rewards to the child gauge https://arbiscan.io/address/0x39d71EE5c97Ff25c3812790f1129Ab060ee66B1b on Arbitrum,] for the pool https://arbiscan.io/address/0x21f132ade35684b230af974b80b5bfd2678ebd80 (surge yUSD/ waArbUSDCn).

Motivation:

We have recently upgraded our architecture and have deployed new pools with v2 yUSD tokens on Balancer. Users are migrating from our old pool to new ones.

This pair on Arbitrum has historically grown to $700k as compared to current $150k across new and old pools and by enabling gauge rewards, this pool will attract additional TVL, benefiting both protocols while creating one of the highest-yielding stable opportunities on Arbitrum.

This integration creates synergies between YieldFi, Balancer, and Aave, boosting activity across all three ecosystems.

Protocol Description:

yUSD is the yield bearing token by YieldFi deployed on Base and is backed by stablecoins like USDC/USDT/USR/wstUSR that strategically allocates assets across blue-chip DeFi protocols to generate 10-20% yields (currently 10.24% APY). The product features daily yield distribution, institutional-grade security, and full on-chain transparency.

waArbUSDCn is the wrapped version of Aave's interest-bearing aBasUSDC on Arbitrum, which allows users to earn yield from USDC deposits in Aave.

Specifications:

Governance: YieldFi operates with a MPC wallet

Oracles: https://docs.yield.fi/resources/oracles

Audits: https://docs.yield.fi/resources/audits

Centralization vectors: The primary centralization vectors include the MPC custody and professional team management of yield strategies (necessary for optimal returns)

Market History: yUSD has maintained a perfect positive yieldcurve with no drawdown since launch with zero instances of depegging.
