yield-yak-aggregator: add yiUSD Milk vault on Base

[BlockchainCake]

Adds the newly launched yiUSD Milk vault (BoringVault architecture) on Base.

• Added Base (8453) to CHAIN_CONFIG with a noFarms flag (no classic farms on Base)
• Added yiUSD to the VAULTS array; APY/TVL computed on-chain like the existing Milk vaults

Contracts (Base):

• Vault: https://basescan.org/address/0xB5803023B8fa8BFe7d64E373297dFaA24e3B5962
• Accountant: https://basescan.org/address/0x0D7e98D765E19760499670ba674079442451eeb8
