Standalone: set PYTHONPATH=AIRFLOW_HOME to match the production image

Standalone mode previously set PYTHONPATH=AIRFLOW_HOME/include only, which
diverged from the Astro runtime Docker image. The runtime image sets
PYTHONPATH=AIRFLOW_HOME (see astro-runtime image/Dockerfile), making every
subdirectory of the project root importable as a namespace package — e.g.
`from include.utils import x` and `from dags.my_blueprints import Extract`.

Because standalone only had include/ on PYTHONPATH, imports that work in
production (and pass `astro deploy --parse`) failed when the same project
was tested locally with `astro dev start --standalone` or
`astro dev pytest --standalone`.

This change aligns standalone with production by setting PYTHONPATH to
AIRFLOW_HOME. Existing `from include.<module> import …` imports continue
to work (include/ is still findable as a namespace package under
AIRFLOW_HOME). Users who relied on flat `import <module>` from include/
will need to switch to the prefixed form, which is what the official
docs already teach (https://www.astronomer.io/docs/learn/airflow-importing-custom-hooks-operators).
