fix(single): align cover breadcrumb with the article title

With a featured image the breadcrumb sits under the title inside the cover
overlay, but its first icon started 6px left of the title's left edge.

The overlay rule carried an extra `padding: 0` that this theme added on top of
the reference. The same node also matches `ul.breadcrumb { padding: 0 }`
(0,1,1 specificity), which outranks the base `.breadcrumb { padding: 0 8px }`
(0,1,0) — so the reference's `margin-left: -6px` nudge was applied with no
inset to compensate, pulling the whole row 6px to the left.

Writing the inset back as `padding: 0 8px` on the overlay rule restores the
reference geometry: -6px + 8px nets +2px from the panel edge. The global
`ul.breadcrumb` reset and the video footer variant are untouched, so archive
and video breadcrumbs keep their current padding.

Tests: new case in the single-cover contract suite pins the 8px inset (and the
global reset); cover suite 12/12, widget suite 829/830 with the pre-existing
frontend-lifecycle failure.
