fix(admin): replicate reference post-feature settings page 1:1

- Rewrite post_list/feature schema (PHP + JS) with the reference theme's
  field set, order, defaults and dependencies; print/PDF toggles dropped
- Move the migrated reference fields off the post-page schema (lightbox
  six switches, post like, default view/like ranges) to kill the dual path
- Map PostDisplay::get_post_page_settings() to the new keys without legacy
  fallback: imagelightbox* (pc_s/m_s checkboxes merged), post_like_s,
  post_default_mate ranges, article_nav + article_nav_mobile_nav_s
- Wire article_nav runtime: content data-nav/no-nav gate with per-post
  override, mobile drawer TOC box, imgbox_type config
- Seed random views/likes on new posts from post_default_mate ranges
- Keep the print stylesheet enqueued unconditionally (no switch); drop the
  dead print/PDF settings and needs_print requirement
- Add post-feature settings reference contract test
