fix(wifi): Fix WiFi setTxPower and getTxPower (#9862)

* fix(wifi): Fix WiFi setTxPower and getTxPower

We need to wait for the interface to be started in order to be able to set/get TX Power. Code was returning too early, so calling the functions after `begin()` resulted in failure.

* ci(pre-commit): Apply automatic fixes
