Duplicate Code: Identical Empty State Widgets (EmptyCard and InitialCard)

*Analysis of commit eaf30eabe62f9b178466629c6d3a4c4390e17311*

## Summary

Two nearly identical widget classes exist for displaying empty states: `EmptyCard` and `InitialCard`. Both widgets have identical implementations with only the class name differing, representing clear code duplication that increases maintenance burden.

## Duplication Details

### Pattern: Identical Empty State Widget Classes
- **Severity**: Medium
- **Occurrences**: 2 files
- **Total Duplicated Lines**: 17 lines
- **Locations**:
- `lib/ui/widgets/empty_card.dart` (lines 1-17)
- `lib/ui/widgets/initial_card.dart` (lines 1-17)

- **Code Sample**:
``````dart
class EmptyCard extends StatelessWidget {
const EmptyCard({
Key? key,
}) : super(key: key);

`@override`
Widget build(BuildContext context) {
return Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: const [],
),
);
}
}
``````

The `InitialCard` widget is structurally identical with only the class name changed.

## Impact Analysis

- **Maintainability**: Any changes to the empty state display logic must be duplicated across both files, increasing the risk of inconsistency
- **Bug Risk**: If a bug fix or enhancement is applied to one widget but not the other, it creates inconsistent behavior
- **Code Bloat**: Two files and two widget exports for what is essentially the same component
- **Semantic Confusion**: Having two separate classes suggests different purposes, but the implementations are identical

## Refactoring Recommendations

1. **Consolidate into Single Widget (Recommended)**
- Keep only one widget class (suggest `EmptyStateCard` for clarity)
- Update all references in `lib/ui/pages/home.dart:75-77`
- Remove the unused widget file
- Update the widgets barrel export file
- Estimated effort: 15-30 minutes
- Benefits: Eliminates duplication, clearer intent, easier maintenance

2. **Add Configuration Parameter**
- If there's a planned distinction between "empty" and "initial" states:
- Add a message or icon parameter to the widget
- Create named constructors or factory methods for different states
- Estimated effort: 30-45 minutes
- Benefits: Maintains semantic distinction while sharing implementation

## Implementation Checklist

- [ ] Review duplication findings
- [ ] Determine if EmptyCard and InitialCard should have different behavior in the future
- [ ] Choose refactoring approach (consolidate or parameterize)
- [ ] Update all widget references in HomePage and other consumers
- [ ] Remove unused widget file and update exports
- [ ] Verify functionality with existing tests
- [ ] Add content to the empty state (currently displays nothing)
