Test failed 18 jan 2025

I do the readme.md and installation works, but test fail. I installed python 3.8.20

```bash
nix develop
python -m venv .venv
source .venv/bin/activate
poetry install --no-root
cd fixture
npm install
npm run build:happ
cd ..
poetry run pytest
```

Start at holochain_client/api/admin/types.py line 221, where AppEnabled is defined, and inspect the related type declarations for Python 3.8 compatibility. Run the reported pytest command and check the collection errors in tests/api/admin/client_test.py, tests/api/admin/signing_test.py, and tests/api/app/client_test.py. Done means test collection succeeds and the suite can run.
