* Tweak - Added support for category 'Group of' rules in the block-based cart.
* Tweak - Declared compatibility with the new Custom Order Tables.
* Tweak - Disabled 'Exclude from Category rules' when product/variation-level 'Group of' rules are defined. Product/variation-level 'Group of' rules automatically override category 'Group of' rules.
* Fix - Fixed an issue that prevented checkout when a product with multiple categories with conflicting 'Group of' rules was added to the cart.
