Refactor widget directory structure by organizing tiles and buttons

- Move `GameTile` and `DoubleRowInfoTile` to `presentation/widgets/tiles/`
- Move `CustomWidthButton` and `QuickCreateButton` to `presentation/widgets/buttons/`
- Update import paths in `HomeView`, `GroupsView`, `GameHistoryView`, and `CreateGroupView`
