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.
Make aksrt_settings the sole theme settings store for get_all(), remove
aksrt_seo_settings/aksrt_basic_settings merge paths, point global.logo
schema at aksrt_settings, and delete the retired settings migration page,
route, REST endpoint, and related SPA surface.
Replace the post_list.list admin contract with a dedicated schema module
using Zibll keys (paging_ajax_s, paging_ajax_ias_s, ajax_trigger,
ajax_nomore, list_orderby, post_list_author/time, target_blank). Runtime
derives numbered/load_more/infinite from those keys and applies list
orderby on main queries without legacy dual-write layers.
