Address review on Noctalia-inspired widgets

- nightLight queries hyprctl hyprsunset temperature to detect state
  instead of pgrep, since omarchy-toggle-nightlight keeps the daemon
  running across toggles. Adds a 'toggling' busy flag so repeated
  clicks do not stack the toggle script.
- lockKeys reads each LED individually and emits 'missing' when the
  class is absent, fixing column-shift mislabels on keyboards that
  only expose a subset of the locks. Hides + stops polling when no
  LEDs are reported. Poll interval relaxed to 2s.
- activeWindow right-click now calls toplevel.close() against the
  captured window instead of dispatching killactive against whatever
  is focused at click time.
- Drop unused Common imports from activeWindow and lockKeys.
