Products run: missing records, asset re-run, audit page, category pages

- new vitec:create-missing-products: MGW Diamond TOUGH, MGW Pico TOUGH,
  MGW Pico+ TOUGH and X-View Integrated Displays as visible records
  (teaser drafts, pid and sys_category assignments copied from the
  sibling product; titles equal the Dropbox folder names so the image
  importer matches immediately). IQS4 stays out - its delivery folder
  is empty, question to Joe
- asset re-run via vitec:import-product-images after re-staging the
  Dropbox delivery (the misfiled Diamond-OG banner corrected into the
  OG inbox folder again): new photos for 95-Series, Avedia chassis,
  SFF PRISM and the new TOUGH/X-View records
- new migrations/build_product_audit.php: generates the internal
  product-asset audit at /product-audit/ (same basic auth, same-origin
  thumbnails) - one row per record with thumbnail, detail link, badges
  for hero/photos/texts/resources/datasheets/solutions, flags, stats
  and client-side filters; re-run any time
- new vitec:import-product-category-pages: builds the nine
  /products/<category> pages (frontend layout 9, hero/main/preFooter)
  from the agency "Product Category Pages" workbooks - intro
  paragraphs, Why-VITEC / product / solution cards, the comparison
  rows as ONE text element with a plain table (no comparison CType
  exists; FE styles it), prefooter banner to /contact, full page
  properties, page sorting per sitemap 3.1-3.9; the empty shells #455
  and #457 are reused. Product card links resolve record-first (exact
  title, stripped parenthesis, family alias, unique slug prefix);
  ProductFamilyAliases gains ten category-level family labels. Solution
  cards tolerate US/UK spelling (center/centre, visualization/
  visualisation). Applied and verified live (nine routes, links,
  tables, meta)
- known gaps reported, queued for Joe: IQS4, Media Players (93/94),
  Chassis Systems, Express Backplanes, Accessories & Cables, PCIe
  Encoders, VMS Plugins & Integrations; the Vision family card awaits
  a flagship decision
