Backend of the sub-market template (spec agreed section by section with

the customer workflow in mind: the customer fills one XLSX per sub-market,
an importer builds the page).

- Frontend layout 21 'Sub-Market Page' in the existing
  BackendLayoutDataProvider: six zones, one per Figma section, emitted as
  colPos110..colPos160 - the JSON groups plus appearance.layout are the
  front-end contract (spec clause 7.17). A first attempt via page-TSconfig
  BackendLayouts was the wrong mechanism next to the provider and was
  removed again
- New Content Blocks vitec_markethero, vitec_marketintro,
  vitec_marketinsights (field bags, serialized unprefixed under data);
  the workflow section reuses intro-paragraph + vitec_card flip cards
- Stories gained quote/quote_person/quote_role (Testimonial tab),
  maintained once per story, emitted on every story card; usecaselist
  gained the layout value 'testimonials'
- New plugin vitec_productfeature: one referenced product as a full
  product card, serialisation shared with the product list (cObj made
  protected for the subclass)
- vitec_productlist gained hand-picked product selection: exactly the
  chosen products in the editor's order, category filter ignored,
  visibility filters kept - closes the long-standing single-select gap
- New CLI vitec:generate-submarket-workbooks: one protected customer
  XLSX per sub-market (9 main markets, 25 sub-markets from the Market
  category tree) - dropdowns filled live from the database, named ranges
  as the importer contract, hidden Meta sheet pinning submarket/group/
  record uid, soft character-limit warnings, asset URL fields

Verified end to end on Broadcast & Media: layout-21 payload with colPos110
carrying the hero element and its subline. Spec raised to v1.20.
