feat: port cms standard layout into trade-pro

Task 10h (last regular layout). Design sources: cms applications.astro +
support.astro (generic content pages). Common form = PageHero (eyebrow/h1/
lead + in-page anchor button + cover bg) then content area.

- The structured sections in both sources (application card grid,
  FeatureGrid bands, anchor nav strip, doc cards, FAQ) are HESU dictionary
  content, not layout - not ported (fake data across sites). The platform
  standard page content is the rich-text body: section structure is carried
  by the body's own h2/img/tables (10g decision), typeset via the 10d
  sf-tp-article-body layer double-attached with sf-tp-standard-body.
- Empty body hides the body section and the hero anchor button (cms
  isRichAbout ternary); empty cover/summary hide bg/lead independently.
- Breadcrumb Home > title per platform page-level convention (10e/10f);
  support's trailing Cta stays covered by pro.html pro-end-cta.
- Zero new CSS rules: applications.astro itself ships no scoped styles and
  the template is pure composition (10c hero / 10b breadcrumb / 10a
  section-head / theme.css baselines); decision documented in pro.css.
- Test test_trade_pro_standard_layout_structure: build-flow page entry
  asserts hero/body containers; bootstrap /services/ page (meta.
  page_template='standard') verifies the template is not route-bound
  (explicit meta beats route-prefix inference) and the empty-data hiding.
