Create an invoice.

    This will (let's imagine) let the API user (some external developer) create an
    invoice.

    And this path operation will:

    * Send the invoice to the client.
    * Collect the money from the client.
    * Send a notification back to the API user (the external developer), as a callback.
        * At this point is that the API will somehow send a POST request to the

    city: Annotated[str, Form()],
    files: Annotated[list[bytes], File()],
):
    return {"file_contents": files, "city": city}

Por ejemplo, si el cliente intenta enviar un parámetro query `tool` con un valor de `plumbus`, como:
