This issue's severity has similar reasonings to #252, whereby If we consider the correct permissioned implementation for the `approve()` function within `CapitalPool.sol`, this would be a critical severity issue, because the withdrawal of funds will be permanently blocked and must be rescued by the admin via the `Rescuable.sol` contract, given it will always revert [here](https://github.com/Cyfrin/2024-08-tadle/blob/04fd8634701697184a3f3a5558b41c109866e5f8/src/core/CapitalPool.sol#L36-L38) when attempting to call a non-existent function selector `approve` within the TokenManager contract. Similarly, the argument here is the approval function `approve` was made permisionless, so if somebody beforehand calls approval for the TokenManager for the required token, the transfer will infact not revert when a withdrawal is invoked. I will leave open for escalation discussions, but based on my first point, I believe high severity is appropriate. It also has a slightly different root cause and fix whereby an explicit approval needs to be provided before a call to `_safe_transfer_from()`, if not, the alternative `_transfer()` function should be used to provide an approval, assuming a fix was implemented for issue #252
