fix(header): wire multi-function page-type enable like zibll

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.
