Make uhid module loading conditional and less invasive

Only load and configure uhid module if it's not already loaded:

1. Check if uhid is loaded: lsmod | grep uhid
2. If already loaded: Print checkmark, skip
3. If not loaded:
   - Run modprobe uhid
   - Add to /etc/modules-load.d/helix.conf for boot auto-load

This prevents unnecessary system modifications and is less invasive.
