Disable import map on cloud (#5642)

## Summary

Disabled ImportMap generation for Vue/PrimeVue dependencies to optimize
cloud deployment performance by reducing 600+ HTTP requests to 8 bundled
files.

## Changes

- **What**: Commented out [ImportMap
entries](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script/type/importmap)
for Vue, PrimeVue, and related packages in [Vite
configuration](https://vitejs.dev/config/)
- **Performance**: Reduced from 600+ individual files to ~8 bundled
chunks with proper compression
- **Deployment**: Improved cloud load times by eliminating excessive
HTTP requests to `static/assets/lib/` directory

## Review Focus

Temporary optimization approach and extension ecosystem compatibility.
Verify that core extensions remain functional without ImportMap-based
Vue/PrimeVue imports. Long-term solution should implement CDN cache
headers and etag for frontend version rather than disabling ImportMap
entirely.

## Context

The ImportMap plugin with `recursiveDependence: true` generates
individual files for every PrimeVue component, creating performance
bottlenecks in cloud deployment. This selective approach maintains the
ImportMap system for future extension API imports while bundling
framework dependencies normally.

## Restoration Path

To restore full ImportMap functionality, uncomment the entries in
`vite.config.mts` and verify extension compatibility before production
deployment.

+      // TEMPORARY CLOUD OPTIMIZATION: Vue/PrimeVue entries commented out for better performance

+      // This selective approach bundles Vue/PrimeVue normally (~3-5 chunks) while preserving

+      // - Cloud load time improvement: significant reduction in initial requests
+      //
+      // LONG-TERM CONSIDERATIONS:
+      // 1. Extension ecosystem: Core extensions don't import PrimeVue directly,
+      //    so this change doesn't break existing extensions
+      // 2. Future extensions: May need ImportMap for dynamic Vue component imports
+      // 3. Deployment optimization: Implement proper CDN cache headers as permanent solution
+      // 4. Hybrid approach: Could selectively enable ImportMap for specific packages only
