We don't need `nlohmann_json::nlohmann_json` explicitly because it is
already a `BUILD_INTERFACE` of the `iceberg` library. Could you double check?

We don't need an extra `std::optional` here because an empty map can be
considered empty.

Review Comment:
I'd suggest to add a file like
[iceberg_rest_api_todo.md](https://github.com/user-attachments/files/23044946/iceberg_rest_api_todo.md)
to the `rest` directory to keep track of the progress.

For each class, please add some docstring. We can simply copy the

Review Comment:
We need to include `iceberg/catalog/rest/iceberg_rest_export.h` and add
`ICEBERG_REST_EXPORT` to all classes to export them in the shared library.

Review Comment:
Try to include `iceberg/type_fwd.h` (and remove some other header files
below) to use forward declaration as much as possible. The main point is to
make the compiler run faster.
Perhaps we can also add `iceberg/catalog/rest/type_fwd.h` to make it easy to
use forward declaration of the rest catalog library. It can be a separate PR
later.

Instead of adding `// optional` comment, can we add `// required` to those
required fields?

BTW, this should be `ListNamespacesResponse` to be consistent with the rest
