Soft logout removal (#672)

* Remove isSoftLogout from everywhere except the client delegate
- bump the RustSDK to v1.0.43
- cleanup the app coordinator state machine and login/logout flows

* Merge `succeededSigningIn` and `succeededRestoringSession` into `createdUserSession` in order to simplify the logic
