fix(migration): update UI to handle transformed JSON format

The DatabaseMigration view has been updated to properly handle both live
comparison data and exported JSON format, fixing count mismatches and
field name differences.

Changes:
- Added helper methods in DatabaseMigration.vue to handle both data formats:
  - getSettingDisplayName() for settings with type/did or activeDid/accountDid
  - getAccountHasIdentity() and getAccountHasMnemonic() for boolean fields
- Updated template to use new helper methods for consistent display
- Added exportComparison() method to handle JSON export format
- Fixed settings count display to match actual data state

Technical Details:
- Settings now handle both 'type'/'did' (JSON) and 'activeDid'/'accountDid' (live)
- Account display properly shows boolean values from either format
- Export functionality preserves data structure while maintaining readability

Resolves count mismatch between UI (showing 1 SQLite setting) and JSON data
(showing 0 SQLite settings).

Testing:
- Verified UI displays correct counts from both live and exported data
- Confirmed settings display works with both data formats
- Validated account boolean fields display correctly
