feat(example/lamp): add LAMPScore and configuration support

- Introduce `LAMPScore` struct with additional fields: `domain`, `config`, and `php_version`.
- Define default implementation for `LAMPConfig`.
- Update `Url` enum to use `Url(url::Url)` instead of `Remote(url::Url)`.
- Adjust references in `HttpServer` and `TftpServer` implementations.
- Modify `Interpret` trait implementation to use `name()` method from `LAMPScore`.
