fix(controlcenter): flush stale-cache races in toggle UI

Browse Source 
- Drop rfkill from bluetooth toggle (redundant with D-Bus Powered,
  was causing stale cache on next read)
- Force toggle switch and icon to target state immediately after
  setting, don't wait for D-Bus callback
- Fix nightlight icon race: flip local is_active instead of
  re-querying async kill state
- Guard wifi on_network_ready against ethernet-first device loop
  (emits device-ready per device; wifi_device None on first)
- Share single NetworkClient between main panel and wifi popup
  (eliminates async-init race of two independent instances)
- Strip connected: prefix from wlan label initial display
- Add _pending_toggle pattern to wifi notify handler to
  suppress stale-cache revert; same for bluetooth switch lock
