feat(analytics): configure analytics initialization and app integration

- Initialize analytics service on app startup in main.tsx
- Integrate analytics consent management in App.tsx
- Track app lifecycle events (start, screen changes)
- Update Tauri configuration for production build
- Set up proper analytics shutdown on app close
- Ensure analytics is initialized before other services

This completes the analytics integration setup with proper
initialization and lifecycle management.
