## Fixing Code Review Issues

I have addressed all critical issues from the code review:

### Fixed Issues in NotificationService.swift

1. **Fixed authorization handling** (line 50-65)
   - Changed from switch on Bool to proper `try` block with Boolean result
   - Now correctly handles authorized/denied states

2. **Removed invalid icon property** (line 167)
   - Removed `notificationContent.icon = icon` - iOS doesn't support custom notification icons

3. **Removed invalid haptic property** (line 169)
   - Removed `notificationContent.haptic = .medium` - not a valid property

4. **Fixed deliveryDate** (line 172)
   - Changed from `notificationContent.date` to `notificationContent.deliveryDate`

5. **Removed invalid presentNotificationRequest** (line 188)
   - Removed `presentNotificationRequest` call - only `add` is needed

6. **Fixed trigger initialization** (line 182)
   - Changed from invalid `dateMatched` to proper `dateComponents` for calendar-based triggers

7. **Simplified notification categories**
   - Removed complex category setup using deprecated APIs
   - Implemented delegate methods for foreground notification handling

### Fixed Issues in NotificationManager.swift

1. **Removed non-existent UNNotificationBadgeManager** (line 75)
   - Replaced with `UIApplication.shared.applicationIconBadgeNumber`

2. **Eliminated code duplication** (lines 75-103)
   - Removed 10+ duplicate badge assignment lines
   - Simplified to single badge update call

### Additional Changes

- Added `import UIKit` to NotificationService
- Added UNUserNotificationCenterDelegate implementation
- Fixed NotificationPreferencesStore JSON encoding/decoding

### Testing

Code should now compile without errors. Ready for re-review.
