Fix client ID lookup for official apps

[balloob]

Breaking change

Proposed change

We hardcode the client IDs of the official Android and iOS app so people can authenticate without having their Home Assistant instance require internet to validate the custom callback.

Except that we hardcoded the wrong client IDs 😬

This PR fixes it.

iOS client ID:

https://github.com/home-assistant/iOS/blob/master/HomeAssistant/Authentication/AuthenticationController.swift#L43

Android client ID:

https://github.com/home-assistant/android/blob/f42ab8fa98760924fee63bec86185113f44f333a/data/src/main/java/io/homeassistant/companion/android/data/authentication/AuthenticationService.kt#L11

Fixes home-assistant/android#601

Should we add this to the next milestone? I suspect more users may hit that issue
