WIDGET. (fix) Complete widget rework implementation

Implementation of WIDGET-001 fix:
- widget_bridge.dart: Add freshQuest parameter
- widget_data_provider.dart: Use freshQuest or fallback to DB
- throttled_widget_bridge.dart: Pass freshQuest through
- game_controller.dart: Pass _quest to widget refresh
- app_shell.dart: Pass gameController.quest on foreground

Tests:
- widget_data_flow_test.dart: 10 tests for parameter flow
- game_controller_widget_test.dart: Integration tests
- widget_bridge_test.dart: Bridge unit tests
- widget_data_provider_test.dart: Provider unit tests

Docs:
- widget_fix_code_review.md: 95% confidence review
- ios-widget-testing-guide.md: Complete testing guide
