Stop the narrow-screen menu icon from covering the menu bar items, refs #38251

#Preview2 week - bugs introduced now will need a build patch to fix
The previous fix put the icon at position:sticky with float:right so that it would
follow the right edge of the window while the 1000px-wide bar is scrolled sideways.
Sticky only moves an element that is in the normal flow, and that turned out to be
the problem: the float sits in the same line as the menu items, so at some widths
they wrap out of the 32px-high bar and their labels are drawn below it on white,
and as the window narrows the icon sweeps leftwards across the items and hides
whichever one is under its opaque background.

Leave the icon where the rest of the bar is instead, at the right-hand end, which
is what the rule for wide windows already does.  On a window narrower than the
bar it is reached by scrolling sideways, exactly like the "Help" and "About Us"
items next to it.  It is moved 8px closer to the edge than on wide windows because
the static pages draw "Home" as the 84px UCSC logo rather than the 23px house icon,
which leaves the menu ending only 29px short of the icon.

Measured the bar on hgGateway, the home page, hgTracks and hgTrackUi at thirteen
widths from 390 to 1400px: the icon is inside the bar everywhere, the menu stays on
one row, and the gap between the last item and the icon is never less than 17px.
Hovering "About Us" at 850px on hgTracks, which used to blank every label in the
bar, no longer does.
