fix: Complete static server (bypass Astro preview entirely)

- Use 'serve' static file server instead of 'astro preview'
- Static server has NO host restrictions (pure HTTP)
- Bypass Astro preview host validation entirely
- Astro built to static files in build stage
- Serve static HTML/CSS/JS in production stage
- Fixes ALL host restriction issues (403 + blocked request)
