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".

View > Theme offers Follow system / Light / Dark, stored in the settings.
Follow system uses the desktop's colour scheme where Qt reports it (6.5+)
and is light otherwise. The dark theme is a deep indigo (#1A1D3A panels,
#12142B entry fields and charts).
The palettes live in the new ViewerTheme module. A switch applies at once:
the application stylesheet is set again after the palette so every widget
is re-polished (with a stylesheet active, polished widgets otherwise keep
their old palette); widgets that bake colours into stylesheets use
SetThemedStyleSheet, which re-applies them on ThemeNotifier::changed;
toolbar icons draw their glyph at paint time through an icon engine, so the
ink follows the theme (and stays sharp at any size); charts re-theme and
rebuild. Hard-coded white backgrounds on entry fields and tables are
removed in favour of the palette's base colour.
The idle detector-status badge in the status bar is now transparent instead
of an empty default-styled progress bar.
