feat: migrate HiddenDidDialog.vue with notification modernization and template streamlining

- Modernize notification system with helper methods and constants
- Replace direct $notify call with notify.success() helper
- Extract button styling to computed property for better maintainability
- Add proper TypeScript typing for notification helpers
- Enhance header comment formatting to proper JSDoc format
- No database migration needed (uses passed-in data only)
- Migration completed in 5 minutes (within estimate)

Security: No risks (notification modernization and cosmetic changes only)
Lint: ✅ Passed
Migration: Phase 3 & 4 - Notification modernization and template streamlining
