Product texts: mapping completed; product model: solutions + resources

Two work packages, one deploy.

Workbook field mapping completed (2026-09-18)
- highlights <- g:Technical Highlight (new spec-row component of the
  full agency delivery; composeGroup() is generic, no change needed)
- applications <- g:Why Choose Card (benefit cards as one block)
- seometa <- new composed source x:seometa (Introduction body trimmed
  at a word boundary to ~155 chars - the SEO sheet ships no meta
  description, a trimmed intro beats an empty tag)
- teaser stays the hero one-liner, settling the varchar(255) question
- fix: "Save mapping" now merges over the stored mapping instead of
  overwriting it - an empty dropdown no longer wipes a stored selector

Product model: solutions relation and Resources tab (2026-09-24)
- closes the gaps the full workbook walkthrough exposed (rows the
  import deliberately skips because the model had no place for them)
- solutions: MM multi select to tx_vitec_domain_model_solution
  (tx_vitec_product_solution_mm, relatedprodukt pattern), emitted by
  both product renderers as solution cards in the shared shape
- Resources tab: inline child table tx_vitec_product_resource - per
  entry a type (documentation/support), an editable card title/text,
  an icon (free text with a value-picker seed set) and one link
  (page/url/file/record via the link wizard). Deliberately no Extbase
  model: only the UserFunc path reads the rows.
- datasheets: own MM selection of download records below the resource
  list (tx_vitec_product_datasheet_mm); emitted into the SAME
  resources envelope as ready-made type=datasheet cards (title/teaser/
  icon from the record, url = the public /download/<slug> route, uid
  fallback - private/hidden downloads 404 as everywhere)
- JSON `resources` (detail payload only, like heroimage): list envelope
  {layout, items[]}; a hand-written card whose link is empty or
  unresolvable is not emitted; layout switches to carousel above three
  cards in total
- solutions hybrid (same day, after analysing all 100 workbooks: their
  Solution Cards reference the 8 GROUPS in 98% of cases): new is_group
  flag on the solution model, new idempotent CLI
  vitec:create-solution-groups (8 group records; title source is
  AlignSolutionsCommand::TARGET - now public -, category = the group's
  own category, detail_page = the /solutions group page with -N
  disambiguation). Group records are invisible to the solution list
  and to vitec:align-solutions and only selectable in the product
  relation; product solution cards carry isGroup
- spec raised to v1.18 (7.15 member table, 7.13.3 note, revision row;
  the footer had been stuck at v1.15 since 1.16/1.17)

Requires on the server:
    vendor/bin/typo3 database:updateschema "*.add,*.change"
    vendor/bin/typo3 cache:flush
