feat: Configure vite dev server for staging cloud testing

- Hardcode DEV_SERVER_COMFYUI_URL to staging cloud URL
- Enable Vue DevTools by default for better DX
- Add SSL certificate handling for all proxy endpoints
- Add optional API key support via STAGING_API_KEY env var
- Bypass multi-user auth to simulate single-user mode
- Add comments explaining the staging setup

This allows developers to test frontend changes against the staging
cloud backend by simply running npm run dev without any env configuration.
