Premium Analytics: fix the breadcrumb overflow behind the display:contents trail (#51085)

* Premium Analytics: fix the breadcrumb overflow behind the display:contents trail

The StatsBreadcrumbs wrapper is display:contents, so the route-level
':has(> nav)' workaround from #50970 lands min-inline-size on a box-less
element and the crumb's nowrap min-content propagates again, widening
the whole page into horizontal scrolling (regressed when #51022 swapped
the raw Breadcrumbs for StatsBreadcrumbs). Own the constraint in the
component: the wrapper's DOM parent and the nav — the actual flex item
in the box tree — both get min-inline-size: 0, fixing every page that
renders StatsBreadcrumbs.

* Drop the superseded route-level breadcrumb workaround

The ':has(> nav)' rule targets the display:contents trail wrapper (no
box, so min-inline-size has nothing to act on) and the nav rule is
covered by the component-owned fix — StatsBreadcrumbs' stylesheet is
now the single source of the constraint.
