Hardcode kUSD (id 402) price to 1 in peggedAssets prices

[enerzy17]

kUSD (peggedasset id 402, added in #819) is a USDC-backed stablecoin on Base. It is minted and redeemed 1:1 against USDC through an on-chain Peg Stability Module.

#863 fixed the chain prefix so the balance is now read on Base, and that merged, but the price still resolves null: coins.llama.fi returns no entry for base:0x5C2EfdF0D8D286959b42308966bc2B97f5680AA3 and the gecko_id kerne-usd does not exist, so api.llama.fi shows kUSD with a null price on the stablecoins board.

This is the one-line follow-up I offered in #863: hardcode finalRes["kerne-usd"] = 1, directly beside the existing finalRes["m-2"] = 1 precedent in the same file, so the peg reads 1.00. Because kUSD is 1:1 USDC redeemable through the PSM, 1.00 is the correct pegged price.

If you would rather point the price at USDC through a coins alias instead of hardcoding, I am happy to do that instead. No rush on either.
