Fix Tailwind config: add @tailwindcss/vite plugin and use bun server for production

- Add @tailwindcss/vite plugin for proper Tailwind processing
- Change 'start' script from 'vite preview' to 'bun server.ts' (production-ready)
- Remove postcss.config.mjs (handled by Vite plugin)
- server.ts already configured to serve from dist/ directory
