Details

A config carrying a !backlight widget on a machine with nothing under
/sys/class/backlight (a laptop config on a desktop) hit
expect("did not find backlight device") in Backlight::new, which with
panic = "abort" killed wldash before a window appeared.

The device path is now Option<PathBuf>. A missing device, or a
configured `device` name that does not exist, prints one line on stderr
and leaves the widget in place so layout indices stay aligned: it
renders empty, skips sysfs reads and writes, and ignores clicks.
