Valid high severity, when taker offers are created pointing to a `offer`, the relevant `stockInfoMap` offers are created with the owner of the offer aka `authority`, set as the creater of the offer, as seen [here](https://github.com/Cyfrin/2024-08-tadle/blob/04fd8634701697184a3f3a5558b41c109866e5f8/src/core/PreMarkets.sol#L245). Because of the wrong check within settleAskTaker, it will permanently DoS the final settlement functionality for taker offers for the maker that listed the original offer, essentially bricking the whole functionality of the market i.e. maker will always get refunded the original collateral, and takers will never be able to transact the original points put up by the maker. This occurs regardless of market mode.
