* feat: update chessground to 7.3.0 (add a board (purple), pieces (xkcd, firi) and fixing staunty knight to be aligned center) (#2380)

* Add purple board theme in list (chessground dependency)

* Change chessground version to 7.3.0

* feat(otb): add takeback button (#1642) (#2334)

* potential fix for notification issues on iOS (#2451)

getAPNSToken() is the only iOS specific thing that happens in this file,
so I think there's a high probabillity that the issues are related to
that.

According to
https://firebase.google.com/docs/cloud-messaging/flutter/get-started we
need to get permission *before* calling getAPNSToken(). Currently it
looks like there could be a race condition where the connectivity change
listener fires before we call requestPermission(). Fix this by moving
the ref.listen() below the requestPermission() call.

* Fix register firebase after sign in

And make sure _registeredDevice flag is only set when device is actually
registered.

* fix: remove delay when entering analysis board (#2471)

This is an alternate fix for #1232 which does not need the 500ms delay.

When entering the analysis board, the delay of 500ms before scrolling to
the current move is unexpected for users. With this solution, we can
jump to the current move immedialtely.

* feat: add log screen (#2463)
