emizzle e5bed448ed fix: remove onSignal not overridden warnings
Uninherited `ProfileController` and `OnboardingController` from `SignalSubscriber` as they were not listening for signals from the node.

Added an `onSignal` dummy method in `WalletController` to make the compiler happy. The main app is assuming this is a `SignalSubscriber` but it is unclear if it being used (maybe it's a WIP).
