feat: complete ActiveDid migration for remaining Vue components

Replace `settings.activeDid` with `$getActiveIdentity()` API call across 8 components.
All Vue components now use the new active_identity table pattern.

Components migrated:
- TestView.vue: Update logging to use new pattern consistently
- ShareMyContactInfoView.vue: Refactor retrieveAccount method signature
- UserNameDialog.vue: Update user settings save logic
- SeedBackupView.vue: Update both created() and revealSeed() methods
- HelpView.vue: Update onboarding reset functionality
- ImportAccountView.vue: Update post-import settings check
- NewEditAccountView.vue: Update account save logic
- QuickActionBvcBeginView.vue: Update BVC recording functionality

✅ TypeScript compilation passes
✅ Linting standards met
✅ Functionality preserved across all components

Part of ActiveDid migration following "One Component + Test Pattern".
All Vue components now use centralized active_identity table.
