Setting up gatekeeper on a fresh instance throws a CardConnectionExpection. I assume this might happen because i have now usb card reader attached - still this should be handled gracefully.

Steps to reproduce:

git clone ...
cd gatekeeper
nix develop .
uv sync
uv run fastapi dev

The following error is logged during startup:
