feat(widgets): replicate 12 reference widgets for full Zibll parity

- rewrite schemas for posts, tab_posts, oneline_posts, hot_posts,
  term_cards, term_aggregation, media_cards, combo_info, partners,
  recent_comments, posts_toc and slider_media_combo to mirror the
  modern reference modules field by field (options, defaults,
  dependencies, min/max/step, subheadings)
- port reference renderers: hot ranking with TOP badges, category
  aggregation card, graphic cover cards, partners CSS marquee,
  combo info cards with auto band palette, recent comment list
- rename 分类与标签聚合卡片 to 分类聚合卡片 and restrict it to
  categories (no tags/topics branch in this project)
- drop topics filter fields and the topics query branch; align
  orderby value domain with supported post meta
- add searchable sortable terms admin field type and spinner unit
  suffix rendering
- unify widget pagination and lazy loading on the REST client with
  the runtime-owned ias reveal trigger; remove the legacy
  post_ajax_trigger dual path
- align section-navs TOC with the reference contract (wznav ids,
  3-heading minimum, zib-widget box)
