feat(widgets): phase 3 align post widgets 1:1 with zibll fields
Align the 7 post/card widget business fields with the Zibll
CSF widget definitions in widget-posts.php:
- WidgetMainPosts/TabPostsWidget/WidgetOnelinePosts: add Zibll
`order` (asc/desc) to build_query_args, form, update, REST
payload and query strings; fix load_mode reading $instance in
query_payload/widget().
- HotPostsWidget: add `target_blank` (form+update+REST+render
href target), wire into query_payload base_qs.
- WidgetTermCards: expand range caps to match Zibll spinners —
pc_row/m_row 1..12, height_scale 20..300, mask_opacity 0..90
(form+update+render+REST).
- WidgetTermAggregation: add `order` (asc/desc) + `favorite`/
`rand` orderby, expand count 1..20, fix `like` meta key to
`_aksrt_like_count` (form+update+render+REST).
- WidgetAjax: propagate target_blank (hot-posts), order + caps
(term-cards/term-aggregation) through REST instances.
- Fix WidgetMainPosts query_payload/widget() using $new_instance
(undefined) instead of $instance for load_mode.
AKSRT pay_type (reading/download/gallery/video/vip/any) is the
semantic equivalent of Zibll zibpay_type (1/2/5/6).
Acceptance: php -l clean on all 7 files; audit-admin-contracts
exit 0; all files <=487 lines. Phase 3 done-when marked.
