Closes #
Currently, any change to a FastAPI endpoint requires manually restarting the Docker container.
This PR switches the dev container from gunicorn to uvicorn --reload, enabling instant code reloading without restarts.
Note: gunicorn --reload does not work reliably with FastAPI (see benoitc/gunicorn#2339). The recommendation is to use Uvicorn for development. This introduces a minor difference between local/dev and production (which still uses Gunicorn), but the productivity gain far outweighs the divergence.
Also, for this PR I am following the convention of
LOCAL_DEV=truethat we use for the web.py container.Technical
