Fix real tab-bar-icons-vanish bug, dropdown popup color, wheel/Montiert swap

The reported "whole tab bar disappears when hiding labels" bug was real,
just one level deeper than first checked. .tabbar.ohne .tab span{display:
none} targeted the label span, but the icon is also wrapped in a <span
class="tabpille"> - a bare "span" type selector doesn't care about class,
so the icon's own wrapper collapsed too. Confirmed by measuring the <svg>
directly (0x0 bounding rect) after a live screenshot showed all 5 tab
buttons empty. Fixed with :not(.tabpille) in both stylesheets.

The Modell dropdown was still bright despite the color-scheme hint from
the last commit: a <select>'s opened option list is rendered by the
browser/OS as its own surface, entirely outside the page's paint tree -
confirmed when a screenshot call hung 30s trying to capture it open.
color-scheme only gets partial credit there; explicit background-color/
color on <option> is what Chrome/Firefox/Edge actually honor for the
popup rows. Added that, verified via getComputedStyle since the open
popup itself can't be screenshotted by this tooling.

Swapped the wheel photo (now right-aligned via margin-left:auto on the
now-correctly-square .bildbox.radbild) and Montiert (already left) per
request.
