Fix HID timeout/EINTR errors and relative icon paths

- Treat "timeout" and "interrupted system call" from ReadWithTimeout as
  non-fatal — hidraw on Linux returns errors instead of (0, nil) for
  both, causing false device-dead detection and reconnect loops
- Resolve icons_dir relative to the config file when the path is not
  absolute, so the service finds icons regardless of working directory
- Installer now copies bundled icons to the config dir on first install
