Cards visible in the FE; /products cards wrapped into 33/33/33 grids

- the freshly attached card images did not show: text_only is the
  explicit no-image variant, so vitec:attach-card-images now flips a
  card to "vertical" whenever it carries (or receives) an image; and
  the new placeholder PNGs sat in the sshfs 770 trap - fix-asset-perms
  covers them, with public/product-audit added to its targets
- new generic vitec:wrap-cards-grid --page=<slug>: wraps a page's cards
  into vitec_cols_33_33_33 containers (b13 columns 221/222/223), three
  per container, section-aware - every top-level intro paragraph starts
  a section, other element types close it, so the category headings on
  /products keep their grids beneath them. Existing grid containers are
  pooled and reused, surplus ones hidden
- the first apply aborted mid-move and left a half state (15 empty
  shells, three cards moved; diagnosis migrations/check_grid_447.php,
  kept) - v2 repairs such states by design: global container pool,
  hard asserts after the create pass, try/catch around the move pass,
  and a final "no card left top-level" verification
- applied on /products and verified live: 38 cards in 15 grids
  (sections 5/7/3/6/2/4/2/6/3 -> 2/3/1/2/1/2/1/2/1 containers), order
  intro -> grids -> banner -> faq intact, children delivered in the
  known items/contentElements shape
