Fixed display and flow issues in lessons, quizzes and rank exams

In lessons, dealing and text no longer continue in the background while the mode menu, conversation history or AI chat is open, and resume where they left off when closed.

Daily quiz reviews now replay from preflop so you can follow the action up to the decision, and "Replay" is now labeled "Review". We also fixed quiz completion occasionally failing.

Closing the rank exam now returns you to the play screen. We also fixed the label of the explanation's ask button, small layout misalignments, and leak analysis failing to save.
