The right end of the display toolbar now carries three "A" buttons for the
100/125/150 % font sizes and a light/dark switch (a sun with a half-filled
disc), so both settings are visible without opening the View menu. The size
buttons and View > Font size stay in sync through JFJochViewerMenu's new
SetFontZoom / fontZoomChanged; the View > Theme tick follows ThemeNotifier,
so it moves when the toolbar switches the theme.
With Qt 6.8+ an explicit Light or Dark choice is also requested from the OS
(QStyleHints::setColorScheme), so the title bar macOS and Windows draw
matches the window, as apps with their own theme switch do. Follow system
withdraws the request first, since Qt otherwise reports the requested scheme
instead of the desktop's.
The image counter reads "1 / 1800" instead of "1/1800".
