Improved Scry functionality

- Visual representation of cards going to top/bottom
- Visual representation of card order (topmost cards going to top)
- Possibly - Drag and drop
- Allow switching of choices up until the confirmation (unlike current implementation, 1 misclick and the scry order is wrong)
- An "I don't care" option - ex. order of cards on bottom, and/or a "keep cards on top of library in current order" option

The issue names no files or tests; start by locating the current scry functionality in the Java client. Review how scry choices are presented and confirmed, then define acceptance criteria for visual card order, revisable choices, optional ordering, and any drag-and-drop interaction.
