Render a Solidity write function (non-payable or payable) as a typed form: function name header, one AbiInput per argument, an optional msg.value input for payable functions, a "Send" button wired through the Tx.Status state machine, and a status badge plus tx-hash link below.

Like every primitive in this lib, the component is stateless -- the caller owns the args, the msgValue input buffer, and the txStatus and passes them in on every render.

A complete write flow looks like this:

-- in update
Send fn ->
    case resolveArgs model fn of
        Ok args ->
            ( { model | tx = Tx.update Tx.TxSent model.tx }
            , web3Cmd
                (Send.encode
                    (Send.writeCall
                        { contract = tokenAddress
                        , method = "approve"
                        , args = args
                        }
                    )
                )
            )


        Err _ ->
            ( model, Cmd.none )

    , payable = Nothing
    , txStatus = model.tx
    , onSend = Send "approve"

    , pendingLabel = "Approving..."

    }
