feat: add useSafeChainsListValidation, tokenSortConfig and privacyMode (

#4860)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so

your changes:

* What is the current state of things and why does it need to change?

* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
