refactor(web): use Radix Checkbox and remove memoTypeStats

- Replace native input with Radix UI Checkbox in TaskListItem for better accessibility and consistent styling
- Remove memoTypeStats tracking and display (link count, todo count, code count)
- Remove StatCard component and related type definitions
- Simplify statistics to only track activity calendar data and tags
