feat: implement seed phrase backup reminder modal

Add comprehensive seed phrase backup reminder system to encourage users
to secure their identity after creating content.

Core Features:
- Modal dialog with "Backup Identifier Seed" and "Remind me Later" options
- 24-hour localStorage cooldown to prevent notification fatigue
- 1-second delay after success messages for better UX flow
- Focuses on claim creation actions, not confirmations

New Files:
- src/utils/seedPhraseReminder.ts: Core utility for reminder logic
- doc/seed-phrase-reminder-implementation.md: Comprehensive documentation

Trigger Points Added:
- Profile saving (AccountViewView)
- Claim creation (ClaimAddRawView, GiftedDialog, GiftedDetailsView)
- Offer creation (OfferDialog)
- QR code view exit (ContactQRScanFullView, ContactQRScanShowView)

Technical Implementation:
- Uses existing notification group modal system from App.vue
- Integrates with PlatformServiceMixin for account settings access
- Graceful error handling with logging fallbacks
- Non-blocking implementation that doesn't affect main functionality
- Modal stays open indefinitely (timeout: -1) until user interaction

User Experience:
- Non-intrusive reminders that respect user preferences
- Clear call-to-action for security-conscious users
- Seamless integration with existing workflows
- Maintains focus on content creation rather than confirmation actions

+# Seed Phrase Backup Reminder Implementation
+
+## Overview
+
+This implementation adds a modal dialog that reminds users to back up their seed phrase if they haven't done so yet. The reminder appears after specific user actions and includes a 24-hour cooldown to avoid being too intrusive.
+
+## Features
+
+- **Modal Dialog**: Uses the existing notification group modal system from `App.vue`
+- **Smart Timing**: Only shows when `hasBackedUpSeed = false`
+- **24-Hour Cooldown**: Uses localStorage to prevent showing more than once per day
+- **Action-Based Triggers**: Shows after specific user actions
+- **User Choice**: "Backup Identifier Seed" or "Remind me Later" options
+
+## Implementation Details
+
+### Core Utility (`src/utils/seedPhraseReminder.ts`)
+
+The main utility provides:
+
+- `shouldShowSeedReminder(hasBackedUpSeed)`: Checks if reminder should be shown
+- `markSeedReminderShown()`: Updates localStorage timestamp
+- `createSeedReminderNotification()`: Creates the modal configuration
+- `showSeedPhraseReminder(hasBackedUpSeed, notifyFunction)`: Main function to show reminder
+
+### Trigger Points
+
+The reminder is shown after these user actions:
+
+**Note**: The reminder is triggered by **claim creation** actions, not claim confirmations. This focuses on when users are actively creating new content rather than just confirming existing claims.
+
+1. **Profile Saving** (`AccountViewView.vue`)
+   - After clicking "Save Profile" button
+   - Only when profile save is successful
+
+2. **Claim Creation** (Multiple views)
+   - `ClaimAddRawView.vue`: After submitting raw claims
+   - `GiftedDialog.vue`: After creating gifts/claims
+   - `GiftedDetailsView.vue`: After recording gifts/claims
+   - `OfferDialog.vue`: After creating offers
+
+3. **QR Code Views Exit**
+   - `ContactQRScanFullView.vue`: When exiting via back button
+   - `ContactQRScanShowView.vue`: When exiting via back button
+
+### Modal Configuration
+
+```typescript
+{
+  group: "modal",
+  type: "confirm",
+  title: "Backup Your Identifier Seed?",
+  text: "It looks like you haven't backed up your identifier seed yet. It's important to back it up as soon as possible to secure your identity.",
+  yesText: "Backup Identifier Seed",
+  noText: "Remind me Later",
+  onYes: () => navigate to /seed-backup,
+  onNo: () => mark as shown for 24 hours,
+  onCancel: () => mark as shown for 24 hours
+}
+```
+
+**Important**: The modal is configured with `timeout: -1` to ensure it stays open until the user explicitly interacts with one of the buttons. This prevents the dialog from closing automatically.
+
+### Cooldown Mechanism
+
+- **Storage Key**: `seedPhraseReminderLastShown`
+- **Cooldown Period**: 24 hours (24 * 60 * 60 * 1000 milliseconds)
+- **Implementation**: localStorage with timestamp comparison
+- **Fallback**: Shows reminder if timestamp is invalid or missing
+
+## User Experience
+
+### When Reminder Appears
+
+- User has not backed up their seed phrase (`hasBackedUpSeed = false`)
+- At least 24 hours have passed since last reminder
+- User performs one of the trigger actions
+- **1-second delay** after the success message to allow users to see the confirmation
+
+### User Options
+
+1. **"Backup Identifier Seed"**: Navigates to `/seed-backup` page
+2. **"Remind me Later"**: Dismisses and won't show again for 24 hours
+3. **Cancel/Close**: Same behavior as "Remind me Later"
+
+### Frequency Control
+
+- **First Time**: Always shows if user hasn't backed up
+- **Subsequent**: Only shows after 24-hour cooldown
+- **Automatic Reset**: When user completes seed backup (`hasBackedUpSeed = true`)
+
+## Technical Implementation
+
+### Error Handling
+
+- Graceful fallback if localStorage operations fail
+- Logging of errors for debugging
+- Non-blocking implementation (doesn't affect main functionality)
+
+### Integration Points
+
+- **Platform Service**: Uses `$accountSettings()` to check backup status
+- **Notification System**: Integrates with existing `$notify` system
+- **Router**: Uses `window.location.href` for navigation
+
+### Performance Considerations
+
+- Minimal localStorage operations
+- No blocking operations
+- Efficient timestamp comparisons
+- **Timing Behavior**: 1-second delay before showing reminder to improve user experience flow
+
+## Testing
+
+### Manual Testing Scenarios
+
+1. **First Time User**
+   - Create new account
+   - Perform trigger action (save profile, create claim, exit QR view)
+   - Verify reminder appears
+
+2. **Repeat User (Within 24h)**
+   - Perform trigger action
+   - Verify reminder does NOT appear
+
+3. **Repeat User (After 24h)**
+   - Wait 24+ hours
+   - Perform trigger action
+   - Verify reminder appears again
+
+4. **User Who Has Backed Up**
+   - Complete seed backup
+   - Perform trigger action
+   - Verify reminder does NOT appear
+
+5. **QR Code View Exit**
+   - Navigate to QR code view (full or show)
+   - Exit via back button
+   - Verify reminder appears (if conditions are met)
+
+### Browser Testing
+
+- Test localStorage functionality
+- Verify timestamp handling
+- Check navigation to seed backup page
+
+## Future Enhancements
+
+### Potential Improvements
+
+1. **Customizable Cooldown**: Allow users to set reminder frequency
+2. **Progressive Urgency**: Increase reminder frequency over time
+3. **Analytics**: Track reminder effectiveness and user response
+4. **A/B Testing**: Test different reminder messages and timing
+
+### Configuration Options
+
+- Reminder frequency settings
+- Custom reminder messages
+- Different trigger conditions
+- Integration with other notification systems
+
+## Maintenance
+
+### Monitoring
+
+- Check localStorage usage in browser dev tools
+- Monitor user feedback about reminder frequency
+- Track navigation success to seed backup page
+
+### Updates
+
+- Modify reminder text in `createSeedReminderNotification()`
+- Adjust cooldown period in `REMINDER_COOLDOWN_MS` constant
+- Add new trigger points as needed
+
+## Conclusion
+
+This implementation provides a non-intrusive way to remind users about seed phrase backup while respecting their preferences and avoiding notification fatigue. The 24-hour cooldown ensures users aren't overwhelmed while maintaining the importance of the security reminder.
+
+The feature is fully integrated with the existing codebase architecture and follows established patterns for notifications, error handling, and user interaction.
