WC_Post_Data::invalidate_products_last_modified │ public static │ WC 10.6.0

Invalidate the cached products last modified timestamp when a product post cache is cleaned.

This does not use wp_cache_set_last_changed() because the cached value is exposed to clients via the Last-Modified HTTP header for collection cache invalidation. WordPress core's last_changed pattern auto-seeds with the current time on cache miss, which is acceptable for opaque cache-key salts but would force all clients to unnecessarily invalidate their local caches. Instead, invalidating the cache here allows the read side in ProductQuery::get_last_modified() to fall back to the DB and re-seed with the real last modification time.
