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.
Point homepage getters and tab queries at home_lists / home_exclude_* /
index_list_title / list1 orderby. Support category+topics tab terms via
tax_query, expand the homepage term picker API, and keep facade method
names for existing templates without dual-writing storage keys.
