feat: Implement snooze functionality for notifications

- Added snooze duration setting in SettingsScreen.
- Created DebugNotificationsScreen to view pending notifications and logs.
- Integrated notification logging with NotificationDebugStore.
- Enhanced SimpleNotificationService to handle snooze actions and log notifications.
- Removed ProfileSetupScreen as it is no longer needed.
- Updated NotificationRouter to manage snooze actions without UI.
- Refactored settings provider to include snooze duration management.
