feat: enhance SSR routing and development experience

- Updated the SSR routing to conditionally load development and production handlers based on the NODE_ENV variable.
- Introduced a new dev.ts file to handle requests in development mode, including asset proxying and HTML response generation.
- Removed the not-found.tsx file and streamlined the photoId route logic for better maintainability.
- Added support for Open Graph and Twitter meta tags in the production handler for improved SEO.
- Updated README with new S3 endpoint configuration.
