Extract shared Uniswap ABIs (WETH_ABI, SWAP_ROUTER_ABI, UNISWAP_FACTORY_ABI,
UNISWAP_POOL_ABI), utility functions (isRecord, coerceString, getErrorMessage,
ensureAddress), and the wrap→approve→exactInputSingle flow into a new composable
useSwapKrk(). Both LocalSwapWidget and CheatsView now delegate to this single
source of truth, so swap logic changes only need to be made in one place.
