Feature/603 taker routing

Fixes #603

I also split the otc store into a make-otc and take-otc store.

@coltraneyan There's an activeOrder in the take-otc store you can use in the OrderDetailWidget. You can import it by using useAppSelector like so:

const { activeOrder } = useAppSelector(selectTakeOtcReducer);

Or you could pass it as a prop in OrderDetail to the OrderDetailWidget.
