track cloud-specific onboarding events and add performance optimizations for hosted cloud app (#6158)

## Summary
- Complete telemetry implementation with circular dependency fix
- Add build performance optimizations from main branch

### Telemetry Features
- ✅ Final telemetry events: signup opened, survey flow, email
verification
- ✅ Onboarding mode to prevent circular dependencies during app
initialization
- ✅ Lazy composable loading with dynamic imports for workflow tracking
- ✅ Survey responses as both event properties and persistent user
properties
- ✅ User identification method for onboarding flow
- ✅ Deferred user property setting until user is authenticated

### Performance Optimizations  
- ✅ Tree-shaking enabled to remove unused code
- ✅ Manual chunk splitting for vendor libraries (primevue, vue, tiptap,
chart.js, etc.)
- ✅ Enhanced esbuild minification with console removal in production
builds
- ✅ GENERATE_SOURCEMAP environment variable control
- ✅ Maintained ImportMap disabled for cloud performance

## Test plan
- [x] Telemetry events track correctly in Mixpanel
- [x] No circular dependency errors on app startup
- [x] Survey responses appear as both event properties and user
properties
- [x] Build optimizations reduce bundle size and improve loading
performance
- [x] All lint/format/typecheck passes
