feat: add Locale, Text Scale, DB Schema Version, Device Model to About page (#258)

- Add lib/core/db_schema_version.dart with dbSchemaVersion constant (32)
  so both the data layer and UI layer share the same source of truth
- Add device_info_plus dependency for Android/iOS device model display
- Show Locale, Text Scale Factor, DB Schema Version, and Device Model
  (Android/iOS only) rows in the About screen diagnostic table
- Device model is fetched asynchronously; the widget re-renders when ready
- Update widget tests to assert the new rows are present
