fix(web): keep the primary action bar on screen at every desktop width

The shell sizes itself with min-block-size everywhere, which is a floor,
not a ceiling. Against that indefinite ancestor, the location page's
minmax(0, 1fr) scene row fell back to content-based sizing instead of
being bounded, so the artwork could grow tall enough to push the action
bar off screen — confirmed visually at 1920 and 1024px widths, where the
bar was fully or partially clipped.

Gives the location page its own definite, viewport-bounded height
(reserve = stable top bar + footer + own padding) instead of touching the
shared shell, which other screens still size freely. The narrow/tablet
breakpoint had a second instance of the same class of bug: the sidebar's
auto-sized row claimed its full content height before the 1fr main row
saw any space at all, collapsing the action bar to 0px height. Swapping
which row is auto vs. 1fr — main first — fixes it the same way.

Also re-anchors the four Verbrannte Straße hotspots to painted detail in
the real artwork (cart, roadside grave, road, cracked stones) rather than
the composition-reference coordinates, and lets primary-action labels
stay on one line via clamp() instead of wrapping unevenly across widths.
