Fixed issues claiming learning plan chests and reviewing their results

We fixed the learning plan chest sometimes saying it couldn't be claimed on the first try. Temporary failures now retry automatically, and if the reward was already granted, the saved result is shown.

After claiming, you can view the cards, hand and coins again even if you leave the screen. Redraw results can also be reopened after closing.

To reduce crashes in the iOS app during the chest animation, we made the effect lighter. The confirmation for selectable Premium tickets now shows the ticket's actual number of days.
