Adolfo Reyna 85da419a98 feat(display): night-dim backlight window for screensaver
- DisplaySettings: nightDimEnabled/startHour/endHour/duty
  (default 22:00-07:00 at duty 20), persisted in display.properties
- Display settings page: Night dim switch + Dim from/until hour
  dropdowns + Dim brightness slider
- DisplayIdle: screensaver runs at the dimmed level when the local
  hour is inside the window (wrap-around aware); falls back to the
  regular duty when time is unknown (year < 2025)
