VITEC Import module: Products tab is now a searchable/sortable product
overview. "Edit Product" opens an XLSX upload with per-field source
mapping (component + cell), old/new preview and checkbox apply via
DataHandler; the mapping and manual matches are persisted and preselect
the next workbook. Category workbooks are detected and rejected.
- new: ProductXlsxReader (PhpSpreadsheet), ProductTextImportController,
Products/ProductTexts templates, 4 module routes
- related products: per-pair card text in new side table
tx_vitec_product_related_text (survives MM rewrites), emitted as
`cardtext` in the product JSON; missing MM relations added add-only
- card copy read from Body Copy (D) with fallback to CTA/Card Copy (E) -
the workbooks fill either depending on row type
- product detail page <title> now uses seotitle with title fallback
(provider made singleton and fed from the JSON renderer)
- per-user recent-search badges; last loaded workbook stored per product
(tx_vitec_product_workbook), Edit Product reopens on it
- composer: add phpoffice/phpspreadsheet ^5.9
- diagnostics: migrations/check_workbook.php
