Fixed display and progress issues in lessons, exercises and quizzes

If you reload partway through an exercise, you now pick up where you left off. Opening AI chat during a lesson pauses playback so the lesson doesn't move on behind it.

We fixed card notation breaking across lines and showing suits as letters, the order of answer choices, and hands with one face-down card not being shown. A single question that cannot be served no longer stops the whole quiz from opening.

If you are on the tournament plan, lessons recommended from your leak analysis are now the tournament versions.
