Command dialog title and description are rendered outside DialogContent

Summary

The command dialog renders its sr-only DialogTitle and DialogDescription as siblings before DialogContent. Since the popup content is rendered through DialogContent, keeping the accessible title and description inside DialogContent should allow the dialog popup to associate with both values correctly.

I prepared a minimal patch in a public fork: https://github.com/pidouga-dev/OpenCut/tree/codex/command-dialog-description

Patch

The change moves the existing sr-only DialogHeader into DialogContent without changing the title/description copy or visible UI.

Verification

• bun --filter @opencut/web build
• bun --filter @opencut/web test (currently fails during startup because the Cloudflare Vite plugin rejects the existing ssr resolve.external configuration)
