Added

• Products: CSV import and export — one file, one row per variant, with auto-mapping of Shopify/WooCommerce headings, per-language Name [xx-XX] columns, and chunked processing so large catalogues import without timeouts. Empty mapped cells leave stored values alone, so a two-column alias+price file is a safe bulk update.
• Installer: uninstalling the Solidshop package is now blocked while Solidshop add-on plugins are still installed — the error message lists them, so add-ons are removed first and never left stranded without the core tables and library their own uninstall depends on.

Changed

• Product listing: build cards from the listing row instead of a per-card detail-model round trip (82 fewer queries on a 20-card page); mod_sshop_products gets the same win.
• Product listing: share one visibility predicate between the list and detail queries so a draft, scheduled, or category-unpublished product no longer 404s the whole page.
• Product List menu item: honour the menu item's category selection (was ignored — every menu item listed all products).
• Wishlist: join what the cards read and batch variant options instead of per-row detail-model lookups; one unpublished wishlisted product no longer 500s the page — it is left out like the listing already does.
