Extract payment readers into AKSRT_Settings_Payment_Runtime and store
canonical Zibll option IDs (pay_user_vip_*, pay_balance_*, pay_box_position,
pay_mark, pay_rebate_*, pay_income_*) in aksrt_settings with no legacy
payment_* dual-read. Update PHP/JS payment schemas and VIP sidebar gate.
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.
Move /settings/homepage onto a dedicated REST trait that stores Zibll
option IDs (home_posts_list_s, index_list_title, home_lists, exclude
posts/cats, list1 orderby). Reader exposes both canonical keys and
temporary aliases for existing front-end helpers; save path drops
superseded AKSRT-only keys. HomepageSettings.vue binds to the new
contract while remaining a Vue custom page.
