✨ refactor: streamline SSR setup and remove Babel configuration

- Updated import path for app.server module in SSR hook.
- Removed babel.config.server.json as Babel is no longer needed for async/await transformation.
- Adjusted esbuild configuration to target ESNext and modified output paths.
- Enhanced App.svelte to handle initial content loading during SSR.
- Updated SSR script to load messages synchronously before rendering.
- Simplified build:server script in package.json by removing Babel step.
