Replace the eight inconsistent back affordances across user-facing pages
with a single absolute-positioned chevron pill, so the control lives in
the same screen position regardless of title length or hero content.
DetailBreadcrumb keeps its textual hierarchy path but no longer owns the
back chevron; PageBack does. DetailHero gains a topNav slot consumed by
Movie/Series/Season/Episode/Request detail pages. Non-hero pages drop
their bespoke back buttons and add PageBack inside a relative wrapper.
