`orjson` dependency fails to install in Python 3.13

Is there an existing issue for this?

Expected behavior

Current behavior

orjson is a required dependency because we use ORJSONResponse inside the app:

However, the version of orjson locked in #529 doesn't have binaries for Python 3.13, and so the dependency installation fails with the error below.

Notes:

• ORJSONResponse is actually now deprecated by FastAPI, so we should switch to just using JSONResponse to avoid needing orjson at all
• based on this PR comment from when the dependency was introduced, it seems like ORJSONResponse is not necessary for the current code either
