Subject: [PATCH] Fix EVM token swap pending metadata showing 0

For Thorchain and Maya EVM token swaps (e.g. USDT to ETH) the spend target
nativeAmount was set to 0, so the recorded transaction amount and its fiat and
percentage metadata displayed 0 while the swap was pending. Use the actual token
amount for the spend target; the broadcast contract call is unchanged because
the currency engine forces zero parent-currency value for token contract calls.
