Complete DIDView.vue triple migration and refactor template handlers

- Fix DIDView.vue notification migration: add missing NOTIFY_SERVER_ACCESS_ERROR and NOTIFY_NO_IDENTITY_ERROR imports
- Refactor 5 inline template handlers to proper class methods (goBack, toggleDidDetails, showLargeProfileImage, showLargeIdenticon, hideLargeImage)
- Update notification validation script to exclude createNotifyHelpers initialization patterns
- DIDView.vue now fully compliant: database migration + SQL abstraction + notification migration complete

Improves code organization, testability, and follows Vue.js best practices for template/class separation. All linting passes without errors.

 ## After Migration Checklist
 
+⚠️ **CRITICAL**: Use `docs/migration-templates/COMPLETE_MIGRATION_CHECKLIST.md` for comprehensive validation
+
+### Phase 1: Database Migration
 - [ ] All `databaseUtil` imports removed
 - [ ] All `logConsoleAndDb` imports removed
 - [ ] All direct `PlatformServiceFactory.getInstance()` calls removed

 - [ ] Database operations use mixin methods (`$db`, `$query`, `$getAllContacts`, etc.)
 - [ ] Settings operations use mixin methods (`$settings`, `$saveSettings`)
 - [ ] Logging uses mixin methods (`$log`, `$logError`, `$logAndConsole`)
-- [ ] **Notification patterns migrated (if applicable)**
+
+### Phase 2: SQL Abstraction (if applicable)
+- [ ] All raw SQL queries replaced with service methods
+- [ ] Contact operations use `$getContact()`, `$deleteContact()`, `$updateContact()`
+- [ ] Settings operations use `$accountSettings()`, `$saveSettings()`
+- [ ] **NO raw SQL queries remain** (`SELECT`, `INSERT`, `UPDATE`, `DELETE`)
+
+### Phase 3: Notification Migration (if applicable)
+- [ ] `createNotifyHelpers` imported and initialized
+- [ ] `notify!` property declared and created in `created()`
 - [ ] **All `this.$notify()` calls replaced with helper methods**
 - [ ] **Hardcoded timeouts replaced with `TIMEOUTS` constants**
 - [ ] **Static messages use notification constants from `@/constants/notifications`**
 - [ ] **Dynamic messages use literal strings appropriately**
+
+### Final Validation
 - [ ] Error handling includes component name context
 - [ ] Component compiles without TypeScript errors
 - [ ] Component functionality works as expected
+- [ ] `scripts/validate-migration.sh` shows "Technically Compliant"
+- [ ] `scripts/validate-notification-completeness.sh` shows as complete
+
+### Validation Commands
+```bash
+# Check overall migration status
+scripts/validate-migration.sh
+
+# Check notification migration completeness  
+scripts/validate-notification-completeness.sh
+
+# Check for compilation errors
+npm run lint-fix
+```
