fix: Remove preview/server config from Astro

- Removed vite.preview/server config that was causing host blocks
- Since we serve static files via 'serve' package, this config is unnecessary in production
- Astro only builds static files and we serve them directly from dist/ folder
- Eliminates 'Blocked request' error in production
