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
