Connect header_components_show_on through aksrt_header_slide_is_show with
zibll page-type matching, drop the homepage-only gate, align admin options,
apply nav color, enqueue by is_show, remove dead float-btn schema, and
consume footer_tabbar_single extend mode on post singles.
Wire existing HeroManager/BannerManager into page-display routes and
component loaders, fix banner REST round-trip (show_meta + optional title),
and retarget operator deep-links to the real slide managers.
Move header-slider outside main, render fluid zones once, default the
latest stream to plain posts by date, and cut dual-render/perf waste so
published posts and hero/banner structure match the zibll contract.
