Fix package build to include all subpackages

Updated pyproject.toml to explicitly include magic_admin.resources and
magic_admin.utils subpackages. This fixes the ModuleNotFoundError that
occurred when importing magic_admin from the PyPI package.

The previous configuration only included the top-level magic_admin package,
causing the resources and utils modules to be missing from the distribution.
