Align product records with sitemap V2; product family model; CLI workbook import

- vitec:migrate-product-structure: exact V2 titles, Milestone typo fix (incl.
  slug), QTX100 stray VSN category removed, Aligo record moved to its own
  category with slug /product/aligo, new Aligo Workstation record takes over
  /product/aligo-workstation
- product families (sitemap column K) are ordinary content pages now:
  vitec:remove-family-records deletes the interim landing records again,
  reset_subproduct_flags.php clears the misused subproduct flag (the list
  renderer has always excluded subproduct=1)
- vitec:import-product-workbook: non-interactive counterpart of the module
  import (same reader, mapping and DataHandler path); Arqa imported, Aligo
  re-applied with the corrected capabilities markup
- ProductXlsxReader: new :copy cell selector (Body Copy with CTA fallback)
  absorbs the agency's column drift; default teaser mapping uses it
- ProductListJsonRenderer: selected categories now match their whole subtree,
  results ordered by category tree position, sheet order within a category
- read-only diagnostics: check_product_structure.php, check_productlist_ces.php

+ * One-shot: clear the subproduct flag on ALL product records.
+ *
+ * The flag was set on every classic product on 2026-09-04 while K-level
+ * entries still existed as records. Same-day model change: families are
+ * content pages, the record table holds only classic products - and the
+ * product list renderer has always EXCLUDED subproduct=1 (its original,
+ * editorial meaning), which emptied every product list on /products.
+ * Before 2026-09-04 no record carried the flag, so 0 across the board
+ * restores the original state.
+ *
+ * Usage:  php migrations/reset_subproduct_flags.php
