* feat: Add UI signifying the currently selected wallet indicator

* fix: Product Fix - Add more padding to child wallets list item tile in grouped wallets, fix sort by dragging for general single wallets, and also groups, add animation to trailing arrow icon when tile is expanded or not

* Update wallet group image and change maxLines

* fix: Make group tile expand if it has the currently selected wallet and fix issue with wallet group image
