CVE-2026-56825: Shopper: Missing authorization on product removal actions in CollectionProducts component

A lack of authorization control was discovered on both the per-record delete action and the bulk delete action inside packages/admin/src/Livewire/Components/Collection/CollectionProducts.php. Neither the Action::make('delete') at line 73 nor the DeleteBulkAction::make() at line 91 carries an ->authorize(...) chain. The component also exposes public Collection $collection without #[Locked], so the collection ID is mutable in the Livewire wire payload. Any authenticated admin-panel session, including staff who hold only browse_collections, can detach individual products or bulk-detach all products from any collection in the database.
